i have recently bought a audi s3 8l 2001. i bought it with a f*cked engine and turbo. so iv spent alot of money on a low milage amk engine and recon turbo. got a good mechanic to fit it all and it runs sweet. but when i picked it up it only boosts to about 5 psi. and i think standard they run at 7. so i had it remapped at the weekend thinking this would solve it. it didnt still getting 5psi. theres no boost leaks on it its been tested. when i bought the car the guy said he had the n75 valve bypassed i think to give it more boost. can someone please help as my bank is empty naw, dont want to take it somewhere and get charged a fortune. thanks all!
