So I ran a turbo XS RFL bov for awhile..and then I gave up and sold it.. Lately however I've gone back to the 2g BoV stock till my greddy system gets here (ICps FMIC And BoV) and my gas mileage has gone to hell. I reset my ECU and still my A/F gauge keeps reading that i'm running extremely Lean like.. it even shuts off at times.. Any ideas? Leak in intake system? Short in wiring?
 
Wait if you have worse gas mileage wouldn't that indicate a rich condition :confused:? Could be a boost leak though. Do you see any difference in performance? Are you holding a steady boost level. Good luck finding the problem!
