Good runs!

What are you running for tires?

Get in the 1.79s 60' and you can get to 12.2.

Because you are spinning. Are you doing a burn out until you see smoke in your side view mirrors from each fender well?
Are you loading up to ~2,000rpm before launch?
Try dropping in 2lb increments. You also need to check pressure between each run.

Can you post all the numbers on the slip from your best and worst from that nite?

I have a data base of over 150 S/C runs to compare to.

Are you loading up to ~2,000rpm before launch? No, tried that and the car dose not respond as well
Try dropping in 2lb increments. You also need to check pressure between each run. I"ll try that next time, Ran the previous weekend at 18 lbs and it was worse.

18psi shouldn't be worse, unless the track is slick. Do you know if other cars were spinning out? If not it is not the track.

When I can I get there early and look for the grove on each lane. I also watch other cars run to see who is sticking.

You should not be worse with a 2,000rpm launch. Tell your symptoms to your tuner.
