    8.1/Allison Owner Seeking Tune

    Hey all, first things first I?ve tried searching around about this topic and found either very old posts with dead links or recommendations to go to Blackbear for a tune but far as I can tell he requires you to mail out your PCM and I?d rather just use HP Tuners as that?s what I have.

    Also, if this is in the wrong section please let me know, I didn?t see a section in the forums for the 8.1.

    Now then, I?m looking to be pointed in the right direction to someone who can make me a tune for my truck just to improve performance and potentially economy without switching to a higher octane fuel and without pushing the truck to the ragged edge, she?s got almost 200k on the clock and I just want to wake her up a bit.

    It?s a 2003 Silverado 2500HD 4x4 with the 8.1 and Allison 5-speed.

    Thanks!
