I just picked up a 97 A4, bone stock until we put a boost control on it. Now at about 10 PSI, it's cuttin the fuel...whats the best way to fix this problem? Thanks

 

you chip it and start by reading here:

you can't just throw a boost controller on your car and turn it up, "saftely" ask jeff about that.... i think he ran 14 psi and blew his turbo

 

since you dont have a MAP sensor, your stuck with having to chip it. speedtuning if your cheap, giac if you want the best

 

chip it first or over boosting your turbo will blow it in a very short time.

then be careful if you use a boost controller, manual boost controllers can be tricky and come back and bite you in the a*s if you abuse it even if you chip your a4
