that might be pushin it a bit with the stock turbo. id turn it back a notch to 17-18I just ordered a Cobb turboback erxhaust, Cobb up-pipe, Prodrive cold air intake, and i was thinking of ordering a new fuel pump for a 2007 WRX Does anyone know what a safe boost would be? I was told 19-20 by AMS.
Ill let you know A.S.A.P.I would like to know before hand what they are using to tune the car. With enginuity you could see 18.5 pounds of boost with a good tune. Those numbers are optimistic though and would require a carfull eye to make sure the car is alright in those boost levels.
