Just wondering if I could upgrade to the 7lb pulley on my comptch SC for my 2004. I think I remember reading that I would have trouble doing that on an 04'. And if so, can I just adjust the FPR without upgrading injectors and EMS? Thanks for the help

 

I remember asking this very same question...I was told bigger injectors are a must for AP2's...pm SilverS2k Nic for more info. By the way, I thought you were selling your car??? Regardless, I'm glad you are keeping it cuz it's really nice.

 

Someone out there has to know something about this.......

I asked the same question and got about the same responses. It looks like the 2.2s run out of injectors at 7psi. I decided to go with the stock 5.5 for now then do 10psi with EMS/Injectors a little later.
