STALLS WTF? ( turbo )

[greendazer]

well i just got my turbo replaced and its boosting at about 7 psi but, it idles very very low and if i put the clutch in after downshifting to second to stop it stalls. i dont know what to do. the guy at the shop says its running on an fmu which is bad because theres no way he can control the idle or anything. all i know is that its running on an mp3 ecu. and maybe that is the problem. someone please help me.

vacuum leak? btw you should not run on the mp3 ecu, that can lead to a blown engine, the timming is way too advanced. get a mp5 ecu with a piggyback, or just buy a mazdaspeed protege ecu. ken sells them for cheap. i wouldnt drive the car anymore intill you do. after you fix that ecu problem, then investigate the other problem, if its still there. which it probably wont.

yeah plus 1 on the ECU...advanced timing on boosted engine equals zoom zoom boom fo' sho (do the fo' sho' in Steve Carrell's voice from the 40 year old virgin for effect!)

Move the MAF to the boosted side of the motor for starters.
