It's funny how people blame the chip, when they should actually blame the operator for not monitoring knock. The amount of boost you can run will change with temp, relative humidity, and barometric pressure.
I've never tried Petro 94. I like the 10% ethanol Mohawk/Husky. When Testing Petro/Shell 92 with 92 Mohawk, I could run 3psi more boost with the Mohawk. And another 2-3psi of boost with the Mohawk 94. Mohawk also adds MTBE, which gives more btu output. I've run as high as 22psi straight pump and saw 2' of knock during shifts. I use to go through lots of octane boost(useless), then mixing race fuel with my gas(costly).
You can't beat the newer chips like TT. But the best is to get a hold of Julio and buy one of his Alky kits!
