Dual 3" exhaust?
We started on 87 and added timing until there was spark knock, then backed it off a bit. It still made quite the difference but I decided the next day that I wanted to go for 93 and see what I could squeeze out haha. -

Dual 3" exhaust?
My 98 k2500 is nothing special by any means, but I was 100% surprised in the potential of that truck with just a tune. Granted, it already has a true dual exhaust and CAI, but getting it live tuned on 93 octane you could almost feel it pull harder with every degree of timing he added at WOT... -
