Well it has been a couple years now since Trifecta has figured out how to re enable the AC on the GM Stage 3 and allow modifications through HPT. I haven't really been a huge fan of Trifecta tunes, but I am strongly considering getting the Trifecta GM Stage 3 flash simply for the fact that it mimics the GM Stage 3 PCM and re enables the AC (which is a must). So I figue that it should be a pretty solid tune for the most part (since its a basic copy of GMS3) for those that are not going smaller than a 2.9 pulley or larger than 42s at the moment, like myself.

So are of you all out there still running the Trifecta GMS3 calibration? If so, how long have you been using it, and has it been a pretty good tune with no problems to report?

 

I'm still running it. Almost 2 yrs now and no complaints or problems. I just need one more update as soon as I can get my computer back up and running again.

 

same here ive been running it for almost a year now with no problems
