I'm not sure if it goes in here, but....

I wasn't running as well at Atco as I had at Maple Grove last month. Better conditions, faster track. Best of 12.64 at 112.xx w/ a 13.01 <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> and a few other high 12's thrown in.

Just replayed my a tap files: 3-4 deg KR from 3k-6300 rpm.

Here are the variables:

Used Amoco 93 for the first time that evening.

Had ported MAF ends, they gave me KR, so I went back to stock de screened a few months ago.

Lost my rubber bumper thingy to keep the y pipe from banging the floor. This happens at the end of my burnout and sometime when upshifting.

I'm going to address the y pipe banging, but do I need a PCM reset after the MAF end swap? I've got 1-2000 miles on it since.

 

Most likely the Y-pipe banging.

No, you don't have to reset the computer. It'll learn on it's own.

Moving to Computer Diagnostics & Tuning... <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
