Nelson performance??? superchip?
I have the 6.0 2500hd (06) model.. anybody know if the Nelson tune will give me more power and mpg's!? i have the Superchip of now and im used to it and it feels sluggish again..
nelson rocks. made 150% improvement on my 5.3 verses the hypercraps i owned. go with 80-85% TM removal and you will notice a big difference.
for my Vortec max 6.0, nelsons said they are seeing 30hp to the wheels.
