HI all, I have a stage 2 mapped APY that is currently missing a fair chunk of boost. My gauge shows -25inhg on idle, so I'm assuming no vac leaks, on boost it normally struggles to 8-10 psi , very occasionally it might peak at somewhere between 12-15 but that's rare. Last week it was peaking at 23 and holding
It has a new Bosch maf, tried swapping out n75 with no success. There's no codes present and visually checking boost pipes and the simplified pcv shows nothing suspect. 4th gear run from 2k to as high as I could go on a public road showed a measly 140 g's so approx 175 bhp!
Any ideas or suggestions appreciated,
Cheers
