The times I've seen cars pop through the intake (mine included), it was usually running lean. I see what improvements you've made to it, so what have you done to the fuel system to feed it?

well im not sure about what lbs my injeters r but i was told they were stage 2 i think like 24lbs?

Don't forget fuel system dosen't mean just injectors.....you also need to look at your fuel pump fuel filter, fuel rails etc.

Try 93 octane gas if you are not using it already and try increasing your fuel pressure. If you are using 24lb injectors make sure that the MAF is calibrated for that size. If that will not fix the problem then your computer may need a custom tune.

how can i tell what lbs my injeters are ?

You changed the rockers. I would look into that area. What did you set the timming at? My 5.0 did the same thing the cause was a broken rocker at the 7 cylinder. MAybe you did not tighten a rocker down all the way.
