-- Hot as all get out. Worse weather I've run in to date. Just absolutely miserable.
-- The Atturo drag radials don't seem to be any good. My 60' times were as bad as when I was on street tires. Plus they're a bit sketchy at highway speeds. Could have been the track temps. Maybe the extra HP. Who knows.
-- E85 content was down 15 points.

Some positives:
-- I did set a new PB on MPH in the 1/8th. Only .01 better, tho, lol. But the car did trap pretty consistent 94+mph so I know the potential is there.
-- MSD 2-step works like a charm and simplifies my staging process because I don't need to flip thru a bunch of screens while I'm getting ready to race.

My primary takeaway is that the Katech 103mm throttle body and JLT v2 CAI are a waste of money (for me). As has been stated a bunch of times by the tuning gurus on this board, the 103mm TB doesn't get you anything over a ported 95mm on an essentially stock motor.
Also, the airbox on the JLT doesn't seal up properly in my snorkle and I don't think it seals to the hood well. My IATs were almost 100* over ambient in the staging lanes.

I'll be going back to the ported 95mm and factory CAI. And Nitto drag radials.

What day and time was the run? The weather has been brutal.
