Performance Chip Adding 50hp??
While searching for the best price to purchase either the superchips cortex 2950 or diablosport predator hand tuners I came across a site offering performance chips for the Hummer. SLR Motorsports is claiming there chip adds roughly 50 hp while adding additional mpg with their performance chip.  Anyone had any experience with this company and their performance chips?? Thanks in advance..
