tuning issues

[BoostJunki3]

ok so e85 and a 3.3 (12 psi) and im getting alot of kr......but its never consistent and all over the place and we think its false knock for sure my afr's are 10.5 to be safe the timing set at 18* and i keep getting false kr action.....plugs are 104's at .054......car is lowered (no short db's or spacers) maybe vibration causing false kr. im getting readings as high as 11* so i know its not real or id have serious issues. what do you guys think?

Pull timing see if it stays. If it does it is false if not you have something that needs fixed in the tune.

Yeah if you can get it to knock on E85, somethings terribly wrong.

i think its something to do with my dp......i put in motor mount spacers......but now my dp hits my floorboard/firewall....now i gotta go get that rewelded....its knocking less with the motor shaking less so i think that might be most of the problem....gonna go to a ls1 tb so my intake doesnt go 4 inch then small ass tb to a 75mm inlet on the blower .....
