so ive recently turbod and for some reason it just wont idle right and i cant figure it out, like it will start fine run fine and drive fine but after i hit boost and i let off as going to a stoplight or just stopping all together my car will drop the idle to around 500 and just jump around and i dont know y, and also when it drops it sometimes stalls also, and ive checked my vacuum lines and there fine, any ideas?

oh and ive already gotten a tune, and it boggs down sometimes also, after i start to hit boost

I bought my car with an injen cold air intake ( goes all the way down drives side engine panel ) gready exhaust, and a few other Tod bits like lowered Ect. But it idled rough. Curious if maybe the guy before did a slap job and got the parts on but didn't redo the ecu to compensate for the different exhaust / intake or if a tune up or something would help. Only rough in idle though

Those bolt ons do not require a tune, nor will they significantly effect much in the way the car runs at all. The ECU is well within its parameters with bolt ons.
