Suggestions / HELP !!! please
 

OK.....today was the very first time for me and my car at the track today. I have to say I was very disappointed. My mods are in my sig and my drivetrain is completely stock. I did not use the NOS at all so heres what I need help with. The elevation was 1230' , 77 degress with 75 percent humidity. I made 4 passes and here are the results

1. R/T .656
60' 2.333
1/8 9.540 @ 78.14
1/4 14.450 @ 102.39

2. RT .551
60' 2.316
1/8 9.430 @ 78.30
1/4 14.330 @ 100.45

3. RT .582
60' 2.349
1/8 9.579 @ 77.55
1/4 14.519 @ 99.63

4. RT .699
60' 2.274
1/8 9.512 @ 77.62
1/4 14.459 @ 100.33

These times I know are terrible....but why? My car came with the 16" wheels with 245/50/16 tires and I put 18" 275/35/18 tires on.....does this come into factor? Plus......my car has not been dyno'd and tuned at all yet, which I know I should do really bad. It seemed my launches were solid with little tire spin (Kumho street tires). Could someone give me some direction on this one? Thanks in advance

your 60' times are horrible. those are killing you by about half a second.

I would also put the stock MAF back on it and see if it runs better. it could be screwing up your tune.
