- Full engine service
- Oil cooler guard
- Full Stage 2 Hardware (intakes,downpipes,midpipe)

Cooler weather & better Da deffo will do low 5s once the customer is used to the power as coming from a xdrive car previously we will turn it up on Ethanol blend to push further 👊

Here have this Fully forged m140 & bottom mount turbo kit in for some work, Customer contacted us after having 2 years of head ache trying to get the car runing decent but he just lost all hopes with it.

After booking the car in and him dropping it of to see what state the car was in maybe it was a good thing that it never ran properly lol other wise alot of things could of gone wrong.

Before even trying to make sure it was doing good times we ripped it apar and tidy up the engine bay so it wasnt a fire hazard.

We carried out the following:

- Solder all Motive reflex wiring
- Fix issue with actuator
- Re route oil catch lines so there not running across the hot exhaust manifold
- Tighten Passenger side loose wheel 😅
- Replace all vacuum lines
- Block of all the ports on inlet correctly and not with a bolt screwed into it
- Tidy up the engine wiring harness

After all of this was carried out we done a data log to make sure its all running sweet and decided to do a draggy 😃

Car was doing 7.31 100 to 200 previously

We managed to do a 5.72 100 to 200 in 30degrees of heat.

Customer can enjoy the car as it is for a little while then when his ready we will start tuning with AFR Tuning.

You can see some of the Before & After pictures

Here we have our shop Bmw F80 we recently upgraded our stock dct clutches to clutches as the stock DCT clutches started slipping already and we didnt even start tuning for Ethanol yet.

After fitting the dct clutches we found out the next weekest link on the drivetrain 🤣🤣 we Snappd the Drivers side rear driveshaft.

Temp fix done waiting for upgraded shafts to arrive then we go again 🙏

Rest of the mods are:
- L500

Loaded up the base file upon login car didnt feel right and there was no warning lights was a head scratch moment for abit then we realised who ever fitted rest of the mods trapd the vacuum line for port flaps so they where stuck closed and not opening under load.

Rectified the issue and carried on with tuning.
Once tuning was finished put it on the local dyno for power run and cars making

475 bhp & 571nm torque at 1.85bar & 9degree timing on Tesco momentum 99

Customer didnt want to push the car as he wanted a conservative map till we forge the engine and send it fully.
