    tuner for 2002 gmc Envoy 4.2 I6

    Hi People,

    I'm new here...great site ! Does anyone know where I could find a decent tuner for my 2002 GMC Envoy 4.2L I6 ? I'm interested in adjusting the transmission shift points. It seems that everywhere I looked I can find 2003 and up but no 2002.

    Our software works on 2002 4.2 I6 Envoys http://www.hptuners.com/products/vcmsuite_vehicles.php
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Thanks Bill. Looks a bit involved though. I was hoping to find something handheld, but I may go for it anyway...thanks

    Maybe a dyno tune would be an option. Where do you live? City/State

    I have used HP Tuners on my own envoy and other trailblazers with great results. You wont be disappointed.

    Find a tuner that can tune your truck, I know PCM4Less uses HPTuners to make killer 02-05 P10 I6 tunes. Alvin knows his stuff, has done a TON of these trucks.
