Here we have stock turbo, stock engine , stock gearbox quarter mile record holder for 10.1 now we have gone Top mount turbo kit from using a 6870.

His dream was to hold the stock engine & stock box record for top mount turbo aswell so we are set out to do that before building the engine & gearbox to take it one step further 🙏

This video is on E blend and we still have a little more to turn up and she is singing already..

Rest Easy my brother 🕊🕊

Here we have Honda Integra Dc5 we did k24 frank conversion on few years ago.

Customer contacted us due to not been able to select gears, after removing the gearbox & removing clutch it become clear why it wasnt selecting gears 😅

The springs on the stock clutch had broken of and jammed between pressure plate & clutch disc.

While removing the gearbox we realised the rear engine mount was split so we upgraded that aswell while we was at it.

- Competition Clutch stage 4 clutch kit
- Honda mtf3 gearbox oil
- VibraTechnics rear gearbox mount.

Here we have a 2016 Golf Gti thats come in for stage3 Ecu & Tcu

Mods:

- Garrett - Advancing Motion Powermax 1 turbo
- Intercooler
- Vis hpfp
- ECOTUNE UK - Premium German Software 📈 lpfp
- 4bar map sensor
- 980cc Mpi
- Sports Cat with straight pipe to tips

Car had most of the mods fitted when it arrived we just fitted the:

- 4bar map sensor
- 980cc mpi
- Drill out the fitting for hpfp

We was abit concerned due to having full straight pipe not even a back box due to turbo overboosting as theres no back pressure but sports cat deffo done its job of that so we didnt have overboost issues 😅 But even do the car had tesco 99 in there it was still having very minor timing corrections which didnt look right because the timing wasnt overly advanced and still had corrections. We put it down to rubbish fuel quality so added 2lt ethanol and all corrections cleared which become apparent it was the fuel then further on revisions only cylinder 1 had alot of corrections. Car had fresh plugs so we knew that wasnt the problem we went ahead and removed coilpack for cylinder 1 and inspected the coil pack as that looked "new ish" compared to rest and the pins in the coilpack were burned out as you can see in the picture.

We went ahead and replaced it with a coilpack we had on the shelf and correction for cylinder 1 cleared.

We finished of the tuning leaving it at around 1.8bar of boost which is enough for this sort of setup and theres headroom if he decides to push abit more in the future on E blend or m**h kit.

Currently its sitting around 420/440bhp

Here we have our Single Turbo F80 we have just driven to Portugal, While we was out here we visited our friends over at ReproPower and thought we will get a quick power run done to see what power its making as cars only been road tuned and we had rough idea of power it was making from 100 to 200 times but not actual power figures.

Due to fuel quality been not as good as UK as they only have 98 here and Ethanol content is like 6% where as UK ITS 99 and 8%/9% ethanol content. We could only test map1 as map2 requires Methanol and the m**h tank was empty as i used it up on the way to here 🤣🤣🤣

Car was filled with Shell Vpower 98 and we added couple litre's of ethanol they had laying in the workshop to clean up any timing corrections due to low quality fuel

And the car made 876bhp and 1067nm torq in this heat which im more than happy with for daily map.

Once we return back from our holidays we will be tuning it on Ethanol and try set some good times with the car 👌

Thanks to AFR Tuning 📈 for all his hard work as the map is solid and car only wasted €320 on fuel from UK to PORTUGAL 🤝

Car is also tuned on MHD Tuning

Here we have "JLO" Bmw 140i Xdrive he reached out to us after having some electrical gremlins with the car and couldnt flash his gearbox due to PT CAN issues.

We got the vehicle onto the ramp & removed the Gearbox electrical connector and measured the PT Can at gearbox end strangely with ignition off PT CAN was all ok when ignition was switched ON PT CAN was having a spazzing out.

So we straight away knew som**hing was taking down the PT CAN soon as ignition was switched on.

Instead of stripping the full car apart tracing wiring and not finding any wiring issues we went ahead and removed everything that was fitted aftermarket.

We removed the Motive reflex plug and it was still spazzing out so it wasnt that causing the issue so we repluged it in.

Then we went ahead and removed the UnlimBoost Xdrive controller and soon as we removed that we had comms with transmision control unit & Xhp could identify the tcu now.

So we went ahead and got a read of the map on the gearbox and sent it of to via @303.tuningsuite when his ready he will sort the tcu map out and car will be driving again with out any issues or limp mode.

As the car has 8hp75 fitted for the xdrive conversion from a diesel car so the car is shifting at 4500rpm soon as you try to go over that rpm via manual mode the car throws up drivetrain fault as its not ment to be revving past 4500rpm thinking its a diesel 👌

Once the tcu map is sorted im sure you will hear Marky start fully trolling online again 🤣🤣🤣
