Hey Grimple, have you dynoed your gt3574? If so, what did it put down?

 

haven't yet. got a few more mods to do before I get her on a dyno. currently it's running on the base pfc map. I don't push it hard (if rarely going over 4k rpm). the GT3574 can push just about as much as I would ever want to go. my goal is 400whp on auto transmission. Right now I have it set up so that the car does not get boost until I mechanically alter it to do so (vents to atmo through piping).

Better intercooler piping, boost controller, WGate, and greddy elbow with BOV are sitting here in the closet. They'll be installed next... THEN I should be ready to tune/dyno it. It's taken me a bit since the previous owner installed some questionable mods w/o any precautions. Learning curve.


time and money: I never seem to have either

 

Just wanted to check and see if others who purchased this had anything to add to Grimple's initial "review" on the harness.

Did you get back control of the Hold button along with smoother shifting?

 

There are lots of automatics running around with our harnesses now. It does exactly what we say it does, it maintains the hold feature and shifting is normal via the stock engine and trans ecus, while giving you complete tunabilty with the Power FC.
