Only reason I brought it in was my CEL was on, I scanned it, and it came back secondary o2 sensor. The dealer ended up replacing the thermostat, so hopefully they didnt flash anything, but thats what the code was showing.
so far, no codes and its been a week.

I changed the air filters upfront to K&N's and also I cleared out the rear cats(2ndary) and resonators...The air temps out side were probably at least 10` cooler tonight and my best was still only a 12.3 at 114? I even got a better 60foot time @ 1.94/???

Here is how the time slip read:
R/T 2.742(I sat there till I was ready to go)
60' 1.947
330 5.267
1/8 7.991
MPH 89.85
1000 10.343
1/4 12.314
MPH 114.54

WTF Are my 20inch wheels holding me back that much or I am just crazy slow here? I figured reading all your times here I would be much faster.
The car feels faster and when I switched out the air filters I hear the whine now where before I did not hear the SC. But I figured just the air temps outside helped me run faster and my mods look neglible in performance...>Keep in mind too that I feeel more confident driving it and am doing better there too....
WTF!!!!

I dont think 20s will kill 80whp but if you have a set of wheels try those and see
Your 20s aren't costing you that much - trapping 114 is low for a stock car, much less a Stage 2. Something is not right. Traction/burnouts/etc have a minimal effect on your trap speed. Your car isn't running right for the parts it has. You might want to strap down to a dyno and look at your graph and air/fuel chart. You may also want to datalog the car to check your IATs.

Your car should be running at least 116mph 100% STOCK at the end of the 1/4.
Most people with stage 2 run 11.6 @ 120-122mph.
I didn't know you have never changed ur pump, even if its not shutting off the SC it will probably help
