After reading a few replies in other threads about how a larger throttle body on a N/A vehicle can cost performance, I decided to throw my factory in and give it a whirl. Upon startup I immediately noticed that the engine came down from the rpms alot quicker than with the 75mm. Took it for a drive. Shifting into 2nd and third gears with traction control off, it felt like the traction control was kicking in. A complete bog down until it got some momentum. I dont know if this may be because the chip is tuned for the larger throttle body or not. Put the 75mm back on and it was kicking like always. Any inputs out there?
