AccessPORT

Yes, I have an AP. I am very happy with it. There was an instant difference in hp and torque. Gas mileage for some went up, for me its a little less than before (but I hammer the go pedal more after the AP).

I'd recommend it. You might want to visit the forums at

My wife uses an AP on her car. Her car was pretty quick before going to stage 1. I was able to stay with another stage 1 car or beat stock ones. Going to stage 1 really didn't really help much, just topend. MPG stayed around the same and economy wasn't a help either. Stage 2 is a total different world; so much smoother, faster, easier to drive, MPG increased 1 to 2mpg. I also recommend buying it.

Accessport is a very good product, however if you REALLY want to control every aspect of the tuning, its hard to not at least consider a TurboXS UTEC or Vishnu Exede, both offer more tuning flexability from my understanding.

what does the AccessPORT and other products mentioned here do?

No, if you want to control every controllable parameter, the Accessport would not be the way to go.

Of course, with all that control, comes responsiblity. You'd better know what all those "aspects" do, how the interplay, and where to stop with each, before you blow your engine--- because YOU are the safety net!

A good analogy is having an investment portfolio based on mutual funds, versus individual stocks.

Hi David, I had Cobb AECU for abt a yr, and then upgrade to Stage 2. Stage 1 was a pleasant bump in power. My 02 WRX has intercooler hoses and a Prodrive axleback at the time. You won't be awed by the ~30HP increase, but the car will drive smoother and the power kicks in at earlier RPMs. I keep gas records and didnt see any mileage drop from stock (~23.5mpg). If you're looking for a set-it and forget-it upgrade, I definitely recommend Cobb.
