Have a 97 firebird with a l67 swapped in. Backstory is here.

Goal when I bought it was to run mid 12's with full interior, AC, and be able to be driven 12 months a year in ND winters.
So since I'm too lazy to update everything from the beginning we start from now, haha!
Ran a 13.26 at 101 with a 1.75 60ft today. It was like 80-85 out with a pretty high dew point. By the time I got the tire pressure set in my DR's and got the launch set good the coolant was 210 degrees, IAT's were 110 so there was nothing really to be gained. I was flowing about 5 lb/min on the MAF less and made 2 PSI less than last week when it was 60 out and I was testing it. The heat killed it. I also was not getting the timing commanded by the ECM. ECM commands 10 degrees in the spark table and it was getting 15 at WOT. I bumped the timing up to 18 and it still recorded 15. I gotta see if theres a table screwed up or something or someway to get the timing bumped up to 20 degrees. Just adjusting the high octane table isnt doing it.
Last race is early october so hopefully I can show up with more timing and better weather not heat soaked and shoot for my 12.99. If I can get 12.99 on the setup it has now and add a few more PSI, 5 more degrees of timing, a little weight reduction, and maybe a light stall like 3000 it might get me to the 12.50 zone.
Overall the day was a success. Dropped .75 of a second over the 89 octane and 6 PSI setup. E50 and 10 PSI was cool to play with.
