Tunnig Question

[BAD LS1]

it would matter more at what load your timing was set. 22-23 is most GMs.. it matters when it starts to taper off or where is starts to gain. adjusting those will help maintain alittle more power thats all. and your A/F would help more than the timing. get it more lean and you will have a much better gain.

10hp, it wont see the gains like FI does from timing

and adding 5 degrees of timing from .64 Grams/cyl and below will lean the AFR to the point where it needs to be in the high 12s

I ran a 12.82 last night on this crappy tune. Can't wait to get this thing running at it's best.
