Dang only 400 bhp?.. Not downplaying you but i've seen people with 380 Whp on stage 2+ 93 octane. Was just curious what the bump would be from 95 octane since ethanol is nonexistent where I live. But I run the madditive octanium unleaded with 10 gallons of 91 and run the 95 octane map and have basically no timing corrections and logs look good.
