Those with the MS3 or similar cam Hey guys I have a strange backfire issue upon quick acceleration. This only happens after I am completely off the throttle either from a start or after coasting and then getting on it. This is on my 2000 C5 with mods in my sig basically just the cam and boltons. We have taken out so much timing down low I dont think that it is the problem. What do you all suggest I look at next.

Blacked Out - Ideally, you don't want to keep DFCO disabled as it provides some of your fuel savings. If that was the culprit, try increasing the DFCO timing some as Slowhawk suggested.
