Which still isn't bad for a 2.0 4 pot turbo......

VXR/ST/Megan/MP5 only run between 220-250 at the fly...

Power holds at peak for a lot of revs though 4500-6750 ish...... but 1.7 bar

Very dissapointing, you can see the X is mapped to throw in so much fuel after 3,000 rpm, and it really falls on its face.






the fuelling on that is pefect, the delay until 3000 rpm is the readings from probe in the exhaust stabilising during the run. a flat AFR graph is exactly what you want, so much so that that AFR graph seems perfect.

do you have the same turbo?

as you could run lower pressure with a larger turbo and shift more air
