Easy to install after I updated it. 15 mins total time to install.
Just installed 20 mins ago. I still have my surge but the bottom end power seems better. It pulls like mad on top, but IMO it only feels like 5 or so horsepower overall. Not too sure if my traction control is disabled either as the light still flashes at me when the tires spin. For 500 bones I think I could have bought some other goodies to spice it up it a bit. Overall Id give it a 6 out of ten. Maybe after I get some cash together I will throw it on my local dyno before the tune and after to really see on paper what this tune can actually do.
