    04 GMC first tune help

    hey all,
    i just built my first tune and ran it while it felt like an improvement id like someone with a little more knowledge than me to take a peak at it. this is all new to me im just working off hpacademys videos and my 11 years experience wrenching so im open for any and all inputs!

    the specs on the truck are
    stock turbo
    sac 45s
    afe intake
    stock transmission
    ppe up/ down pipe
    4 in exhaust


    im not looking for big hp mostly trans safe and solid for towing since i have a 9k camper behind me frequently.

    didn't look at it....yet.... but I just got sac 45s. running stock tuning with 40btdc timing. so far they seem pretty decent. also got the lbz pump bareley smokes at all, pretty shocked really. been wrenching intermittently on my own stuff since I was 16. but new to tuning.... especially diesels. Unfortunately everyone wants to lock your ecm and I hate that idea.
