Hey there. I just bought an 07 Silverado Classic, with the VortecMax package, which as you guys probably know comes with the 6.0L gas v8 and the i believe 4L80E tranny, correct me if I'm wrong on the tranny. I was told your tuner made something like 57 hp on a Denali with the same motor, now that sounds a little on the high side to me, so can you guys give me a real world scenario of what I'm looking at power increase wise? I know it'll improve shifting, and it'll be a great asset when I'm towing, but what am I looking at power wise?
