Hello, Have a 05 2500hd 6.0 that I'm trying to get tuned. I'm getting better but still have a lot to learn compared to some of you guys. Right now I'm still in SD because I cannot get a MAF .CFG to work with the wideband for some reason? In my scan most when you see the 15ish A/f ratios most are coasting. The first bit is just cruisin around then theres a WOT pull towards the end where I'm getting some decent knock. Please take a look at my scan and tune and tell me what I need to do. Please don't kick me in the dirt as I am new, but I take constructive criticism well. Thank you
