I still have the stock air box in place, my question is can I run a down pipe, mid pipe, and catback safely with my stock ecu?

 

I wouldn't run those mods without a fuel controller or aftermarket ECU on my car running a stock fuel system. You could get a boost-dependent fuel regulator and bigger secondary injectors if you want to keep the stock ECU, but it's financially not the best choice.

You can boost spike with those mods on the stock turbos.

It's your car though, so you can try to push it by running on the stock ecu. If you have those mods, it's only a couple hundred dollars for a fuel controller and few hundred for something more advanced like Greddy eManage.

it will most likely start to run lean...i think your better off replacing the mid piple with a hi-flow cat

 

Thats cool just wanted to make sure, I currently have just a DP and CB with stock cat in place. I guess I need a ECU upgrade, PFC here I come. I just dont trust anyone here in the chicagoland area with the tuning duties. Any sugestions?
