Will it pose a negative effect if I go back to my stock throttle body ad keep the 70mm egr spacer? I have no need to do this, It is just a few less things for me to change. What is the downside to having an oversized throttle body if it is not needed? Loss of hp/tq or both? The first time I went to the track, I had headers, .040 overbore, 3.73's, flows, and the CAI. I ran a 14.8@around 93mph, I think. This past time, after all that is listed, I only knocked off .2 sec and gained no mph, could this be part of the problem? Also, what effect woult it have if one of the sensors in my mass air looks fried? Would it even run if it was, or would it just not run to its full potential? Thanks for the replies. Also, the first time I went to the track, I was shifting at about 6200 prm, last time it was about 5500 rpm.
