Hello, Im having issues guys. I just got done with a na to tt swap but my car does not idle right. It wants to die, it starts sometimes.

Idles bounces back and forth. I have a dual maf set up with translator, with a ecu set up for a single, so the switch on the translator is set to single.


Car runs rich, doesnt want to pass 3k rpm(maf right?) I have tried 3 different OEM mafs plus 2 aftermarket ones, no effect. I have switched to the single maf configuration and nothing.


I noticed that my boost controller (AEM) is reading -11 to -14 vacuum. So I'm wondering if that issues is related to a leak. Anyone thoughts?
