I wouldnt even bother changing the computer, there are plenty of xr6 turbos running huge amounts of power with a standard computer, that should be information enough, next time if you ask a dumb idiot a qst youll get a dumb ass answer as such is the case here.

And if your after 400 rwkw you can get that out of the factory turbo...it will just be at its limit that's all.

Stick with the factory ECU if is going to be a street driven car. Everything works and you can still tune for both Power and Economy.

just as I thought, the to4z lets me not have to do things twice

so is any one on here using a stand alone

Not with 400rwkw; maybe 600+ rwkw and if you wanted something like CDI.

Not worth the effort and cost IMHO.

I had a Motec M800 before Edit was available.

No way in the world would I ever use a stand alone - not unless its a bosch motorsport ecu and you've got 20k for ECU and anther 20K for ecu calibration and tuning. The biggest problem with most aftermarket ECUs is that alot dont support drive by wire and cam phasing. And while some may say they can do it they wont do a very nice job of it.
