When did you last clean the imrc's ? They could really mess with powercurve

i didnt know cleaning maintenance was required with the IMRC's. can someone give me a link for a "how To" to do such? it makes sense if there is some build up in there which would also explain its its struggling. BUT, i don't think that would cause the white smoke especially during decel between shifts.

I'm going with IMRC's being dirty also given that they open at 3250. Google IMRC cleaning I bet there is 1000 different discussions on many Forums.

The tune was done by Tom D.P Inc in allentown. he has a 2000 Saleen twin screw Supercharged and some other toys that he has done tunes on. here is a picture of my dyno sheet and i had posted on the first page 3 videos of my dyno pulls. My only question is can dirty IMRC be the cause of my white smoke? I just figured it would hurt the cars performance...Thanks for ALL the responses guys. i was really down in the dumps after that guy told me all that. and let me know if this dyno shows you anything as far as possible diagnostics. thanks!

white smoke= leaky or blown head gasket. i didn't really see any white smoke after your dyno run on ur vid. if anything there was alittle puff of exhaust fumes, which most cars have after heavy acceleration. your exhaust valves are prob alittle worn, no bid deal. however, your car looked like it stumbled alittle bit a couple times according to the dyno. maybe bad spark plugs. get yourself a haynes manual before you go tearing into the car.
