Default Question for those who have the APR Bi-Pipe and X Chip
My friends and I installed my Bi-Pipe the other day. I am running an X-Chip. After installing the Bi-Pipe I am seeing my boost levels at redline fall to approx. 11 lbs under WOT. Midrange till like 6000 RPMS she holds at like 15-16 lbs. I think it used to stay at like 14-15 at redline before the Bi-Pipe installation but am not 100 percent sure. Could there be an error in installtion that would cause this, or does everything sound OK?

Sure you don't have any leaks?

Default Did you run a pressure test to make sure you're not leaking boost? Always a good idea after messing
around with the intake parts of the car.

Or maybe the bipipe has a hole in it like someone once said they had.

Are you sure you didn't bind up one or both of the o-rings on the throttle body?
