I'm running about 11 to 11.5 psi pretty safely. Logs look good and we are making 707 at the wheels with Toohighpsi port injection, Maggie 2300 from SCOL on E85 (E65 in our area). I had a 16ss that we exceeded the amount of boost anyone should run on a stock Lt1, I had to pay the fiddle for that 18 psi we were running. However that motor can take a lot with good tuning, Vp race fuel and a lot of Meth/water injection. I did get 180 passes out of that motor and 12,500 miles so it can take a lot, but you'll eventually have to make a choice, lower boost for real longevity or breaking pistons cause you were drunk on drag racing and boost. Take the longevity.
