Last Saturday, I recorded two 1/4 runs with the '97 MP PCM on my scanner
(15.8 and 15.5 ... both at 89 mph). I did a quick look at the outputs to see
what was causing the slower times. In addition to noting that the spark
advance
was lower than the '96 MP PCM throughout the run, I saw, just as I was
doing the
1-2 shift at about 5000 rpm, the computer retard the timing from 26 degrees to
18 degrees. Why, I don't know unless it was the only way to get EPA approval.
I re-installed the '96 PCM and promptly ran a 14.9 at 92 (best trap speed to
date).

No problems with mine. If anything, WOT is too rich.

Boy, what size tires are these? My OE tires were 215/75 x 15 with 3.55 SG.
My
drag radials are 26" and now, with 3.92 SG, my effective gear ratio is about
4.20.

Not familiar with the r/t pump package ... what is it?
