I just got my urs4 chipped 2 days agofrom MTM/Lehmann... the car was driving very rich afterwards and i felt a big difference, after 2 days the car lost its power, now its even slower than before, I know im leaking boost somewhere...but where is the question? I did change the bypass valve once i got the chip cause i know that was fucked.... any suggestions would be appreciated... thanks

 

Its probably your stock throttle body boot. i had to replace mine too, get the SAMCO boot. its alot stronger, and it will hold up better if you keep on modding your car, which you will

 

do you mean the 3 piece boost hoses? the one from Turbocharger to cross-over pipe ? Maybe that's what it is if thats what you mean, thanks though i will take them off my car and inspect for any rips...
