Default Swap chevelle, new tune new times

Went to try the new tune and 25% ud pulley out

DA was 2930 at the last time listed on dragtimes.com but humidity went from 50% to 68% by 11pm according to the weather updates on my girlfriend's phone,

Ended up making it to finals for a 2nd place win. Lost because I broke out, but I was happy because it was a new best even though I lifted

60ft 1.791 (spinning noticeably)
330 5.068
1/8th 7.857
mph 84.66 (car was trapping high 88.x mph when I wasn't lifting)

Car weighs ~3700lbs+ and was running on 275/50/15 Nitto 555r with 22psi

Previous best was 7.902@ 87.8 mph in 2600DA with the same 60ft, not lifting any

Does this seem about where I should be for my mods?

Cam peaks at 6000, I'm shifting at 6300 so the FAST might not be helping a ton more than a ls6 intake would but I got it cheap.

Sweet car. Congrats on the runner up finish. I agree on tire psi being to high.

I've tried running them at 18psi before and pulled the same 60ft with them still rolling over several times.

Drop down to 14-16 if you still spin at 18 psi.
