I only make 331/385 with dci, catless dp and no meth. I was really hoping for the 350 range like so many others.

I make 389/440 with meth flowing.
From your meth log it looks to me like you can make a bit more boost (0.5 to 1.5psi) across the range safely...even on these hot summer days with 97 deg IATs. This *should*equate to more power. Using the standard 65 start boost maps with a 50/50 meth/water concentration and catlezz dps, i would get 18psi for some reason. When I changed to 70 start boost i hit 19psi and lost about 5 RWHP on the dyno. I created a custom boost profile to ramp boost from 13psi to 18psi @ 4,500 rpms and then ramp down to 16psi at redline which gave me the best results. Have you played with the boost settings at all?
