I would recommend the Compushift system. This will give you the most for your money. You do not need a laptop to program it. The best part about the system is that it comes with everything including a harness that has factory GM plugs. Check out bowlertransmissions.com or give them a call. The system can be purchased with or with out the display. Bowlers will set up the program for your specific vehicle, that way if you don't want to speed the extra $200 for the display/programmer you won't have to.

There are a couple of controllers on ebay at the moment including a Compushift which is by far the best design out there. I've been working with them for the last month or so and I am sold on their concept. I'll be installing one in my car. Not only does the display allow you to tune without a laptop (I used to prefer a laptop, now I see that that's nuts), the unit also has a built in dyno simulator and handling accelerometer. There is nothing else like it. Worth every penny.

As for GMPP, it IS a TCI unit. If you go TCI, try to find an older 377000. They just integrated with FAST and it seems there are some bugs in the system. I had a customer pull his TCI and go Compushift. I don't know what's up with the bugs, but I insist on 100% satisfied customers. So until I see results, I will unfortunately have to keep away from the new TCI units.

That leaves:
Compushift: $1095 w/o display or $1280 with display --or--
Powertrain Control Solutions: $850 A very powerful controller with some insanely cool features like boost calibration trim that varies trans calibration based on boost or vacuum.
GMPP: Not sure if GMPP is still selling the old style TCI or the new style.

Feel free to call me and pick my brain.

These controllers are not cheap by any means. But for what they do, these controllers are actually incredible values. Of course, there's no real way to know that until you plug it in and try it out. But once you do, you'll be blown away by their capability.
