My latest outings at the track have been extremely disappointing and I cant figure it out. Last year I ran a 14.972 @ 92.32 with a 2.274 60'. That was with mac pro-chamber, cat-back, shifter, and mac intake.
Since then i have done 3.73s (from 2.73s) - PI cams/intake - Accufab 75mm t/b - P&P c&L plenum - and a 93 octane tune resulting in a best run of:
14.725 @ 95.06mph with a 2.257 60' ....
This was at the same track and I know its not my driving .... its the same as before ... better 60' chirping 2nd and 3rd ......
The only thing i can think of is that the tune is no good - It was done by American Muscle ....
I believe between the gear swap and PI cams/intake i should have picked up alot more......
What do you guys think? I know the PI cams are correct and didnt jump a tooth or anything during install... new plugs were put in then too.....
Theoretically im very disappointed with this... what do you guys think it could be?
Are the tunes from AM usually reliable? Should i try data logging my A/F ratio? I thought i would be low 14s easy... esp going from 2.73s to 3.73s
