[PETER.T]

when i disconect the cooler piping it runs ok..but when i conect it again it does it...so im thinking afm...

Can you describe what you actually did as disconnecting cooler piping to make it run ok doesnt make any sense. Your cooler piping is your intake tract, by removing it your introducing unmetered air, ie air introduced to the engine once its been measured by the AFM.

my afm isnt on the pressure side i.e in the cooler piping its on the vacume side i.e where the turbos suck from .when the cooler piping is conected it wont let me hit boost, but when i disconect it the "car" alows me to rev it out in all gears and i can here the turbos working fine and hiting boost. the problem occurs when i conect the piping.
