I need some advice... Once I start up my car, its fine... revs fine and everything. After I get into boost, and say slow down at a stoplight, right at two grand it idles really funny and jerks the car. All I have done recently is put on a new tb... another stock tb. Could it be some ajustment I need to make on the new tb? It only starts jumping and idling funy @ 2k AFTER I have been into boost.. Im baffled.. any help?

EDIT: Just a FYI.. Im running 310's witha 8:1 disk in the FMU, and a inline fuelpump in the way of fuel management.

EDIT 2: I also had replaced the IACV. The IAC motor isnt hooked up, and never has.

it sounds like a vacuum leak
i would triplecheck the tb gasket, this way

go take the car out, reproduce the problem
bring it home
let it idle and spray some carb cleaner or somthing to see if it changes the idle.
