Huge congratulations to our customer Adam for taking his clean VT down to Calder Park Raceway Raceway last night.

Not only was it his first time ever at the track, but he also drove an impressive 11.95 @ 124mph on street tyres driving the car to and from the track as well.

An awesome effort all around. 👏

We had Michael reach out with something a little different in his VP Commodore.

The car gets driven regularly and even does towing duties, so he wanted to make sure everything was where it should be and see if we could squeeze a bit more out of the combo, as the current tune had a few drivability issues.

With plenty of supporting mods already in place including a water to air intercooler, 8PK overdriven balancer, Mace Engineering Group Stage 2 camshaft, water methanol injection, and a T56 conversion we knew the setup had plenty of potential.

The car had previously made 225rwkw, so we knew there were gains to be found.

We started with a fresh tune, going through everything carefully fueling, ignition, and the methanol controller making sure everything was working together as it should. The final result was 254rwkw and 663nm, all controlled through a VS ECU.

Michael was stoked with the extra power and immediately commented on how much nicer the car is to drive now, saying the “car feels smooth as silk to drive now.”

We had Rob bring his VT Commodore to us that his mate Jerome converted to turbo over 10 years ago, but it was never quite right and they could never get the tune sorted.

The car came back to us a few times while we worked through some issues.

The first time around the car was doing some strange things. After a bit of diagnosis and discussion we decided to spec up a camshaft of our own design.

We supplied them with a complete kit along with a GFB boost controller, which they fitted themselves.

Once everything was installed they brought the car back to us. The new camshaft setup was working perfectly, but unfortunately that’s when we uncovered another issue boost creep caused by the internal wastegate setup.

Jerome then went back and modified the turbo system he had originally fabricated, this time converting it to an external wastegate setup.

As they say, third time’s a charm.With the new setup in place we were finally able to get everything dialled in properly.

The car behaved exactly how it should and finished up with a solid 321rwkw and 854nm, all through the stock auto and still being controlled by the factory Delco ECU.

The boys down at Aussie Car Bogan dropped off an absolutely immaculate VN SS that just wasn’t running the way it should.

With an engine sporting a few unknown mods, backed up by a full exhaust system, stall converter and diff gears, we weren’t exactly sure what we were walking into.

After some solid time on the rollers, plenty of fine adjustments and a bit of keyboard therapy, we dialled it in to a tidy 166rwkW and 509Nm through the factory Delco ECU.

Our returning customer Adam has well and truly caught the boost bug, chasing more power from his extremely clean and tastefully built turbo Ecotec VT Commodore.

He got back in touch with us to see how far we could safely push his current combo while staying within its limitations.

After a few discussions, we decided to step things up by replacing the factory driver’s side manifold with a Hurricane extractor to improve flow and help reduce engine bay temps. We also fitted an upgraded GFB actuator to better control and increase boost.

Once the parts were installed, we strapped it down on the dyno and the difference was night and day. But as always, more power exposes the weak links.

With the extra boost, we quickly found the limit of the 320lph fuel pump. To keep fuel pressure stable where it needed to be, we upgraded to a Walbro Fuel Pumps 460lph unit.

With the new pump in place and everything dialled in, the car laid down 331rwkw and 915nm with the converter flashing to 5400rpm. Curious to see what it would do locked up, we ran it again and it punched out 358rwkw all on pump 98 and still running the factory Delco ECU.

To say Adam is stoked with how much more aggressive the combo feels now would be an understatement.

James got in touch with us to sort out his WN Caprice after the old girl had clocked over 550,000kms. At that point, it was time to freshen things up with a full rebuild.

While it was apart, he also opted to upgrade to a 3.27 diff ratio to better suit the combo.

With the fresh engine assembled and a DOD delete completed, the car was dropped off to us to run the engine in properly, carry out the tune, and recalibrate the shift points to suit the new gearing.

Once everything was dialled in and running spot on, it finished up with 256rwkw and 610nm — more than enough to get the big girl moving the way it should.

James can now sit back and enjoy his land yacht the right way.

We recently had Jet back in with his VY Calais after our last session was hampered by extremely high intake air temperatures, which stopped us from getting any real results from the setup.

Since then, Jet reworked the intercooler system by rerouting it and adding extra capacity to help get the temps under control.

After some discussion, we also decided to step up to a larger blower pulley. The M90 was being overspun previously, peaking at 16.8psi. It now peaks at 11psi and with these superchargers, more boost doesn’t always equal more power.

With these issues sorted, we strapped it back on the dyno and let the results speak for themselves.
Final numbers came in at 233rwkw and 571Nm. While peak torque is down due to the reduced boost, intake temperatures are now well under control and the car feels noticeably stronger across the entire rev range.

Jet is stoked with the outcome and is keen to get out and enjoy the car even more.

After some much needed time off over the Christmas break, we got straight back into it.

Adam brought in his recently purchased l67 swapped VR ute, a build that was completed over 13 years ago and still features all the right supporting mods, including a built engine and a water-to-air intercooler setup.

Deciding where to take the car wasn’t an easy choice, but after plenty of discussions, Adam made the trip over from South Australia and entrusted us with getting it running how it should.

The ute was previously tuned on an 808 ECU using Kalmaker and had made 261rwkw and 607Nm through the T5 manual setup. Unfortunately, the tune had become corrupted, leaving the car essentially undriveable.

We replaced the chip and started fresh using Tunerpro

After a thorough check over and some dyno pulls, we achieved a final result of 279rwkw and 563Nm an impressive outcome considering the age and overall quality of the build.

Adam is now pumped to finally enjoy his new ute and drive it all the way back over the border.

Yet another Summernats build we were asked to help push over the line.

When Dave and his mate decided they wanted something a little different, they settled on a manual turbo Ecotec KE70 wagon. Finding someone willing to take it on proved difficult, so they made the 2.5-hour drive down to let us do our thing.

With a tight deadline and a huge amount of work already ahead of them, they contacted us to get the wagon sorted and ready for Summernats. The main goal was simply to have it running properly and reliably, as the car is still running mostly standard driveline components.

We went over the car thoroughly to make sure everything was in check before getting stuck into the tune. It wasn’t the easiest one, but we got there in the end.

Final numbers came in at 216rwkw and 685Nm, pushing through the T5 gearbox at a peak of 11psi. The setup is very basic just a boost tee and a 2.5” exhaust as the priority was keeping it safe and reliable.

With the car weighing next to nothing, there’s more than enough power on tap for now to keep the tyres frying down Skid Row.

Once again, all of this was achieved using the factory Delco ECU.

Sash brought in his extremely clean VN Calais wanting it fully sorted in time for Summernats.

He was experiencing inconsistent idle, over-fueling, and overall poor drivability. With a basic rebuilt engine, transmission and converter, along with diff gears, the setup was already a solid street combo suited to cruising it just needed to be dialled in properly.

After a quick inspection, it was clear the existing tune had far too much ignition timing and was excessively over-fueled throughout.

We got to work correcting everything, resulting in a final output of 156 rwkW and 557 Nm, all managed via a Haltech GM Sport ECU.

In Sash’s words, “It’s a completely different car — what a difference.”

Now he can enjoy cruising and take on the big week that Summernats brings.

Patrick made a recent purchase of a vt l67 with a few mods and was complaining everything just felt off.

Well he was definitely right with the car having a smaller pulley full exhaust and an unknown camshaft.

We plugged in and straight away could tell it was all factory tune so a recipe for destruction.

With some fine tuning we ended on 210rwkw and 456nm with a peak of 8psi.

Now he can enjoy his new ride without any added worries.

Paul got in touch with us to sort his VG, as it had been running rough and proving unreliable, along with needing a number of other repairs. He wanted the car gone through properly and done right.

We were given a list of items to check over, so we started with a full health check including a compression test. Once that was confirmed, we wired the thermo fan to be ECU controlled and fitted a new thermostat, as one hadn’t been installed previously.

From there we checked over the exhaust and repaired a few leaks, adjusted the kickdown cable to ensure the new transmission shifted correctly, and noticed the coil lead had the incorrect end fitted, which was replaced with the correct unit. We also welded a transmission temperature sensor into the pan so Paul can now monitor trans temps.

With the engine recently rebuilt and fitted with some minor upgrades and to future proof his plans we upgraded the fuel pump and injectors.

Once all repairs and upgrades were completed, we moved on to tuning. The final result was 180rwkW and 429Nm. Interestingly, after noticing something wasn’t quite right, we removed the air filter. While this didn’t change the fueling, it picked up an additional 16kW and 12Nm.

To say Paul is happy with the end result is an understatement.

He’s already in discussions with us about further upgrades, and we’re looking forward to having the car back again in the future.

All work was carried out using the factory Delco ECU.
