In tests on my setup there were really only one thing that helped on spool. And that was going leaner during it. I messed with the timing and really got no difference in doing so. I run a assload of timing on 93 octane and 100% meth. I rather run meth because race gas is just to much to run ALL the time on a daily driver. If we did have E-85 around here I would jump all over it. That shit is insane imo.
So now I run 12.5-13.0 on spoolup but drops to around 11.5 on 100% meth and 27psi of boost and 28-30* of timing. Or should I say I WAS doing so. Things are in the works since I put the new AGP delta billet wheel turbo on the car.
