so i finally got up the ***** to change the high and low octane tables and at 2* increments i have advanced the timing to 26* at wot with no kr. and it pulls like a mother im pretty sure i found my missing hp. im going to stop here and try and learn more about tuning and hptuners before i put it on a dyno and try and find mbt.
so in my experience for those who read this and are sticking with the lt1 and 24x conv make sure the tuner doesnt treat it like another boosted ls1 and put 16.5* of timing to it. hopefully they tune to mbt.
i would like to add that i am not a tuner nor do i have a clue what im doing but itll be fun till it goes boom. lol.
thanks for all the info

Ls1 has a 15* valve angle which makes it a more efficient combustion chamber. 23* stuff is generally a lazy setup. That's why we get away with big timing numbers.
lt1s sure do love timing. Im at 26* with meth at 14 psi

Bigcat.... what compression are you at? I'm at 10.25:1, 18 psi, 24* with A/W on E85. Intake temps are typically 90* or lower. Sounds like I could probably get away with a little more timing with my current setup. I'd like to up the boost a couple pounds to 20+, then possibly even up the timing from there.

I am not super familiar with e85 but it's my understanding that it likes more timing than gas. But I would run it buy the boosted guy's on YB and get a feel for what they run.
