ok. I have the only 395/422rwhp/rwtq Ls1 in the land that cant run faster than 13.0. this is killing me. here's the info and you guys can see what you think.
before cam/ls6 int/converter/tuning best t. slips
60ft - 2.036
1/8th - 8.348
mph - 85.23
1/4 - 12.93
mph -108.70 This was at 316/337 rwh.

friday nights run w/mods(dont have this slip so its by memory)
60ft - 1.82 (best so far w/2800 stall)
1/8th - 8.4's
mph - 84-85 (about same)
1/4 - 13.01 (best of the night)
mph - 106 (???) this is at 394/422 rwh. (i know i need to scan the dyno sheet cuz i wouldnt believe it either...)

is it just me or is my car just plain falling on its face??? i have no idea what the problem is. can anybody give me any suggestions here? i got to run an 03' cobra and nosed him out by .125 (13.01 <> 13.125) and it was on street tires. cant have that. Moderators, please put this where ever you guys think it will do the best...

Did you autotap it during your runs? How long as it been since you dynoed your car?

hmmm what was the temp., humidity and barometer readings for that night? What are you shifting at and what is your rev limiter at?

BLKWS6

Them temp outside was about 70-75 i think. high humidity though. but i have run the same as this on days that were 85-90 degrees outside too. no difference in perf.
i had the car dynoed on 7/23/02 when it pulled those numbers. went to the track like 2 or 3 weeks later and ran 13.2's 3's...???
i tried shifting at 5000,5500,6000. rev limit is at 6500. Also just in "d" with the computer shifting at 6. only varied by .2 max
