I noticed ZERO difference swapping to 3.08s to 3.73s without tuning for it, and ZERO difference with a tune for them, but dropped .3 tenths with them.

maybe a little once you get a cam. If I were you, Id stick with it and just use the cut out as power mode since your in Cali.

Your best bet is to have the cutout closed at the beginning then open it after about 2-3 seconds.

Id like to see you actually remember to do that while driving lol

I NEVER remember to do anything after the burnout lol I have forgotten I had it in first gear, many times to turn off my electric fans.
