Correct sir, all I ran was Keith's tune with my basic setup. I have not had any other work done or parts from AWDTuning. Long story short, he's far from me and I'm a busy fella. Point of that was, he knows his stuff when it comes to tunes. I cannot say anything about his motor specs but we've discussed some of his specs and experience. All his specs were on point with what I would build, IF I wanted a NEW 8.7CR motor.
I have gone the custom route for my build, with my parts combo, my purpose of the vehicle, and my budget. If suprise expenses didn't keep kicking me in the nuts, I'd already have their stage2 shortblock installed.
Like all reviews, depends on the source. Just consider where you're getting your information and use your best judgement. Lots of tuners catch heat from stubborn customers refusing to accept they jacked it up. Built never means indestructible.
