mines been doing that on deceleration since before the supercharger install. im still trying to track down the culprit

 

I wouldnt mind that, but accelerating in town and around traffic, sounding like im driving a POS.... getting really annoying.

 

adds to the sleeper look... people think my trucks a pile that can barely push itself cause of the rattles and clanks it makes until it squeels em and jumps sideways.

 

replaced pcv, tps, IAC, cleaned MAF, datalogged everything, cant figure it out. im lost.

 

is the MAF dirty by any chance???

 

Boost bypass, bent/burnt valve, Torque converter?

 

Doubt its a valve issue. Boost bypass works fine... As for the converter, I dunno. Does it if the tranny is 120* or 180... Today it did it leaving the last stop light to get on the highway, in 2nd I floored it, and at WOT it still surged, so that throws out any vacuum problems. But it cleared up within 30 seconds of driving, like always

 

Da*$!!! So I'm not the only one...mine's been doing this as well since day one after the supercharger install. Only does it every now and then. Drives me nuts but you come to a slow idle and it goes up and down. My a/f goes nuts though....just can't figure out why, I have done everything including replacing intake gaskets and still does it....I sure would love to find the culprit myself.

 

If your iac integrator is commanding too much air it will do that... Tell your tuner to fix it

 

Already checked that....no change.....its very rare but does happen so it's hard to track down.

 

would you happen to have a scanner that will allow you to look at the sensors?

 

Yeah I can log all that. Nothing is out of place...?

 

This may or may not be a clue. See last paragraph post # 22. You have deleted your EGR I believe.
