is it just in certain rev range or does it happen in differnt gears?
reason I'm asking is, my car pulls hard like a school boy with a stack of porno in first second and third gear, all the way up to/close to redline. The fourth gear and fifth seems a little lacking in torque. I pu the foot down and the car sound like its suffocating when reving higher. I'm wondering if thats a flat spot or if it is just because of the standard dump/front and cat restricting the air flow when the boost is increased.
