Interesting info so far.

49-75 deg for run 1 << 9.5psi
49-83 deg for run 4 << 11.6psi added fuel KR still
47-82 deg for run 5 << 11.6psi pulled timing and KR went away

LS1Tech consensus seems to be to run an 11.0 A/F, but I have had no issues running 11.8-12.2 on a forged motor with at least 1 method of intercooling.
I'll be focusing on timing and boost also as well as methanol/intercooling more than super rich gasoline A/F to keep my motor happy.

I'm expecting no less than 35rwhp and 25rwtq. I'll post results in about 1-2 weeks. Could be higher. I remember MightyMouse had great results but I didn't see his before # comparison.
Looks like I'll be tuning at 11.5 to 11.8:1 when injecting Methanol, vs. 11.8 to 12.2 on gasoline. I believe it allows an additional 3-4* timing above your gasoline tune. Adds around 4 octane points to your fuel depending on Mix. I think most injection setups end up with an 80% gas 20% Meth mix.
Also have heard it can drop charge temps from 80-150* and might show as +2psi due to denser colder air.
With 100% Meth it's supposed to be the same power as 116-118 race fuel due to cooling effects.
