Re:Detonation Problem

i'm using the 12.1 fmu from Vortech. the website said it was good for 10psi and under on stock injectors. all i have is a boost gauge.

I'm having a hard time believing you are running lean with a 12:1. Very strange..... ???

Re:Detonation Problem

Re:Detonation Problem

i went to a local tuning shop and they said even though i have a fmu, i should look into upgrading it, i'm picking it up for $130 something.
