Is your engine alright with the engine being so lean? Detonation doesn't sound good. |
435 was with stock TB, modded stock airbox (another intake mod that Quality is going to release in the future), and w4me tune. We think the tune was a mixup because it did not have the fuel changes you would expect. Basically a mislabeled 2.55 pulley tune but in all honesty I have no idea.
We did not get detonation when it was running lean only after we started giving it the fuel it needed. That was only once and he shut it down.
I remember the A/F ratios were 10.35 and 13.x just not sure which one is when it was running lean. I think it is the 10.35 but I am prolly wrong.
