Damn dude I'm sick of this crap! I want burnouts not broken stuff!

Anyway here is some info regarding the spark tables between an LQ4 and LQ9.

The first picture is a low octane table from a 2006 LQ4 in a 2500 work truck.

Here is the low Oct table from an LQ9 in a 2006 Esky

Here's a bit of info off the HPtuner forum about swapping LQ9 tune onto an LQ4

If you look at them there isn't much more than a degree or 2 between them in most areas so the Lq9 shouldn't be that crazy sensitive to knock. I fear the tune is jacked because that dude doesn't know wtf he was doing or even worse............ The cam is degreed wrong :sorry:

Wouldn’t the cam have to be off by a tooth which would be obvious and the engine running like complete shit?

The cam can go in more then 1 way? I've heard of degreeing a cam, but I never cared to find out about it.
I actually burned rubber coming out of the parking lot :D. IT WAS AMAZING!!

I would assume so but I really don't know, never seen it in person I'm just spit balling here lol.

The fact it has enough balls to burn rubber low in the rpm is good. It could very well be your injectors are maxed out, I know I've read a lot that stock 6.0 injectors are close to being maxed on a stock motor. What RPM does the breaking up/loss of power appear to start at?

Flex fuel 50 lb injectors can be found for less than $120 but it’s hard to say if his are maxed out. https://www.lsxceleration.com/delph...K85wChSKnF7XcFqwonRw8Kp4gKdwvu1hoCVo8QAvD_BwE
