Interested to hear your opinion. Tried on 2 of my trucks. Total junk imo. 2000 and 2004 models. Maybe newer ones are better.

I used then in my 01,and 04 GMC I used Diablo sport in my trailblazer SS, a few different ones in different rides that I cant remember the names. They all seem to do as they claim. This time the price was right on this one so far doing as claimed. As started the write up in in the 14 section in the performance thread. It be interesting to here what didn't go as claimed on yours.

The one I used on my '02 Silverado didn't do much. It went when I sold the truck.

There wasn't as much to work with on an 02 as now. On my 01 and 04 I did cold air, headers and hypertech last. By raising the max RPM the trans. pressure, shift points and advancing the timing for 93 fuel it woke the truck up.

Mine was all stock. 2000 was 5 speed, 4.8 so no trans adjustments. 2004 is 8.1 with Allison. Supposed to get better fuel milage, but actually got worse. Couldn't tell any difference in performance on either.If i recall it was not capable of trans adjustments for the allison.

I was already happy with the performance on E85, Im more interested with AFM, firming the shift a little and seeing the trans. settle down a bit. The AFM was raised I may remove it, the shifts are firmer jury still out on the trans settling down, this is day one and so far just hammer down up the road and back.

Hopefully you will have better luck then. Let us know what you think.

As I stated in the 14 section, the programmer is working as advertised, more of an old time feeling with the throttle, transmission shifting is more direct seems to know what to do no hunting. I slowed down to 45 MPH and nailed it, it was all go no hesitation.

Update I knock the TM down to 50% from 75%, firm shift no jarring. Everything working as advertised very pleased.

Update 3, gas mileage, no change in town but im still driving a little more aggressive up to speed, so considering that it must be doing better on gas instead of going down. Going on a trip soon so we will see on that, don't expect better gas mileage, but they claim an improvement. Turned up the tm to 100 % to see if it would turn the tires on the 1, 2 shift it did then I turn it back down.

Which version did you purchase? I am very interested. It gives you the option to go back to stock any time, correct.

Max Energy Econ Power or Max Energy Power?
