New times after pcm4less chip
For anyone who remembers my post a little while back about my mini-ram install, I was complaining about my 1/4 times and how I actually slowed down. Well, I'm here to appologize. I got a chip from pcm4less, and made minor changes to F/P and timing and ran the car on Wed. I dropped just over 2/10ths off of my 60' and .6 off the 1/4 and almost 6mph. All three times match consistant to each other so I'm assuming the entire power band is much flatter. The only thing I have to complain about now is the shift from 2nd seems a hair too early because the rpm's seem a little low in 3rd and it take a second to catch back up. Other than that I'm happy until the heads and cam replacement
These runs were at Raceway Park Englishtown, NJ
Run before tune:
R/T-.455( I think)
60'-2.05
1/4-14.03 @96.2mph
After tune:
R/T-.323
60'-1.82
1/4-13.42@101.9mph

Could be the ratio drop in the trans between the 2nd and 3rd.
You can try leaving in 2nd then manually shifting to 3rd at a higher RPM. Manually shifting can take a bit longer for the shift to hit, so you'll have to compensate for that.
