Anyone make a performance PCM for the Envoy/trailb

[gotitbad]

I am looking for a PCM like the wait4meperformance stuff for my 04 envoy....something to help with the torque management, a little more power, and some better fuel economy..anyone know of such an animal??

I know for a fact that there is no performance PCM for the TrailBlazer/Envoy (GMT-360/370) platform, but you can order a Westers tune for the 5.3L V8 and the 4.2L I6 (2002 & 2003 years only as of now). They send you a new PCM with the tune on it and you send them your stock one once you get the replacement, = no down time. Read up on what they do with the tune on their website:

What up Scarab? The 5.3 has been out some time for the '04. I've had mine for probably 4 months. Overall, pretty happy with it in a nutshell. The I6 version just came out. I haven't heard any feedback from any of the guys over at Trailvoy.com yet. Quite a few are anticipating tunes. There's quite a few threads out there on Westers so do a search.
