hows the jetting?

The higher you go the richer it gets, the richer it gets the more turbo lag you have(to add to a crappy rich running motor), ect...


just a quick thought...

yes, EFI no jets...

Still doesnt mean its calibrated roperly though... Could still be running pig rich.

Is the BOV working ok? Maybe compressor stall?

how many miles on it.check all your sensor lines for moister & check you header pipes to see if they are cracked or collapsing.you may need a remapping but i doubt it.

Check your grounds, it might have a weak ground causing it to momentarily miss/ Many possible things to look for, start with what we have given you and move from there. Process of elimination.

Sure sounds like an intake or exhaust leak
