which is the better choice? Aem Ems or Apexi Power FC Commander? I asked this question in the tuning part but no one answered.....im going to get a gt35r turbo kit too so put that into consideration i know aem ems is better but i can get the apexi power fc for a lot cheaper than it retails so help me out...does the apexi power fc do good with a gt35r turbo kit

 

I know both these systems are good and can achieve great results but the hks engine managment I think is better. Ive heard alot of good things about the hks unit and you can actually pass inspection in Ny and other states that require a obd-2 port wich you delete with the Aem and some of the other standalones on the market.

 

I don't believe you would see extreme gains with an EMS. IMO you should stick with the stock ECU and use ECUFlash. This will be the easiest way to get inspected. There are many people that have 500-600whp with a 35r and stock ECU. I have to switch back to stock ECU and run 10psi for 100miles in order to be inspected.

 

Listen to this guy, 500's hp is easy on the stocker. I doubt you need more than that for now.
