My old motor i was pretty aggressive with, the setup was as follows: 2003 290k lm7 with the stock 706’s, arp head studs, ls9 gaskets, slightly stiffer springs, a factory 2000 ls1 cam. I would consistently run 21-23* of timing all the way up to 20-23#’s of boost on pump e85. My ethanol sensor would register around 76-77% ethanol. That setup went a best of 10.1@140 in my 3800+# Camaro. I upgraded to a 2005 l33 that has a ljms stage 2 turbo cam. I am a little more conservative on this motor because it was a little more expensive than the $200 lm7 lol. But i run that one at 17* on 19-21#’s and has gone a best of 9.67@146 in the same Camaro.

Any chance you would throw up or send me a copy of your l33 tune? You have the same cam as I have and I would like to look over a few things on how your timing is setup vs mine?
the computer i use to tune isnt on the internet and i dont like to go on the internet with it cause its the only computer i have. :/ otherwise I totally would!
