New belt on. Filled up with E85 (prob more like E70-something right now)... mixed with my half tank of E50 worked out to be E64.

I'm still intentionally running rich for addl safety, but things are looking good!

I'll probably take about 2% out of both ECU and Reflex MAF and start bumping up the shift points until I feel "good" about things.

At 6000 RPM getting about 9.5 PSI now with the 3.7" pulley, where before it was around 7 PSI with the 4.13" pulley. Procharger ramps up the PSI real quick above 6K engine RPM, so going to make fairly small shift point bumps at a time.

I think I'm seeing the low side fuel pressure dips that radz28 mentioned too now that I've pulleyed down and running more E. Nothing too concerning to me at the moment, but will keep an eye on it.

The pulley REALLY is making a difference earlier in the RPMs too. I can feel it SOTP.
