Went to the strip tonight.

you need to launch a lot higher than that. on BFGs (235/60/15s) i was leaving the line at 3500-3700 RPM with a pretty similar setup (shelby underriders though). still not stellar 60fts, 1.90s, but a lot better than 2.0+ this was with about 12-15lbs in the tires and a pretty burly burnout.

also, shift a little higher. you don't shift AT your HP peak, you shift ~10% past it, so around 6k.

if you aren't afraid of destroying your T5, try power shifting. it was worth a tenth in the 1/8th mile and 2 tenths in the quarter for me.

I would shift at 58-6000. try that and see what happens.
