Just got my PCM in the mail for my dad's 2005 GMC Z71 with the 5.3. Cost is great, but I was a bit disappointed that there wasn't some kind of breakdown included concerning what can be expected. I told them I was interested in more power on the street, better mpg, and firmer shifts while still maintaining comfortable driving. I'm just a bit scared I guess you could say because all I got was a box with a PCM and a short list of instuctions, not even a receipt. I sent them an e-mail asking for a more detailed breakdown, but have not gotten a response. Has everyone had good luck with these tunes? And how important is it to have the crank sensor adjusted right away? Thanks!

 

im sure they did what you asked them to do.. nelson`s tune comes the same way instructions on how to put it in and thats it..im sure it would take them quite a long time to sit down and type up what they did for every customer...im sure if there is something your not happy with they will fix it. i know nelson does.

 

if ur gonna do mail-in tunes, go nelson or wheatley. I've heard bad things about wait for me tunes.
