I bought my first Subaru(also my first turbo car) about 9 months ago. i have Cobb AccessPort, AEM CAI, an Invidia V3 downpipe, Perrin Dual Tube Cat-back, Perrin LW Pulley, and ACT StreetLite Flywheel. I want to get a ProTune and some dude with a pumped up 06 WRX who seems to have some knowledge on subarus and tuning them said that an AEM CAI system is not compatible with a Protune with the Cobb AP. Is this true and is it better to go with a different system? Thanks....Frank

 

I might be wrong, but I think you can protune anything with a Cobb AP. Honestly, you can stick with you stock box; with a high performance drop in filter and you wil get more gains. Intakes start to mean something once you start upgrading to a bigger turbo. See if you can get the SPT Intake, carb legal and tunable!
