It comes pre-loaded with a number of off-the-shelf tunes for various conditions or stages of tune. For example, a Stage 1 tune works with an otherwise stock car, while a Stage 2 tune for my WRX requires an aftermarket J-pipe, a popular and effective power adding mod. You can customize features like a shift light, launch control, and flat-foot shifting, run performance tests, diagnose and clear OBD2 trouble codes, and configure up to six different gauges to monitor engine parameters in real time, as well as log them.

It cost me more than an entire VW Jetta. I admit, a stretch goal of mine with this car is to one day get the same hp out of it as the STi while maintaining the superior daily drivability of a non-STi WRX.

Even with just a little bit of throttle the car wants to take off like a rocket. Among the parameters I can look at in the center screen — even without the Accessport — is throttle position. This makes the WRX difficult to drive conservatively. At lower speeds and throttle input, it always wants to go, go, go. My Accessport came with v3.

I have 94 turbo k, ard white tune, cone filter, mbc 14lbs, cat delete. I want to go faster plain and simple Ill have lucky do the tune of course and can make my own dp blah blah blah Where can i get a 20g and how much?

I dont care if its used or not but does anyone know of anyone??? Just dont know where to get one and was wondering if someone could help a guy out. Because im not ready to ruin the rods yet. Why put a bigger turbo on when you cant run it at its full potential? I just want something like the 20g for now. Suggest you go with an 18T I didnt mean bigger? I meant better over all. And its the smaller turbos running high boost at low rpms that really kills rods, not so much the late spooling big turbos.

Thats what i want a slower spooling turbo Im looking at around to play with There are better turbos out there but the 20g, like all mitsu turbos are cheap and easy to rebuild and are water cooled. This a real precision turbo?? I would probably want the 82ar housing for slower spooling correct?? Thats a very goos price real or not has to better than fleabay turbos.

Stop trying to buy a turbo that spools slow, by the proper turbo for your goals and use a real tune and ebc to control boost. Go with the smaller AR, and get a good tune. And based on what you said, it seems like the HRC 16G would provide all the flow you want. Agreed, ewg will cost a good chunk of money, hrc's 10cm2 units are a ballsy Turbo in a small size frame. Seems like everybody forgot about my exhaust housing I understand that that is pushing budget up a bit more but hey, that's what a forum is for Performance Modifications Search In.
