Turbo upgrade Tuesday!
Another MK8 ST in with us for a Turbotechnics S285 supply, fit and Dyno tune. This car was previously STG2 tuned by ourselves with , but with the mileage creeping up and the performance slowly disappearing with the wastegate bush becoming more perished, it was time to give it a fresh lease of life!
Now is probably a good time to talk about fuel qualities, we are seeing major discrepancies from all over the country in relation to how 99 the 99RON actually is..
There is no magic tricks that can be done and there certainly won’t be any desensitising of knock sensors around here, so we are limited to what we can do at the exact time your vehicle is on the Dyno. Well this car was hungry for the ignition timing, showing good quality 99RON fuel and giving it an impressive final power figure!
Nearly 290BHP and 420NM was the final result👀
Hearing a rattle from your engine bay on your MK8 ST? Car feeling down on power, slightly laggier than what it used to be? Let us put together a package for you to utilise an upgraded turbo!
