David D. of Orlando, Florida, installed a Six-Gun Diesel Tuner and PowerPDA Vehicle Command Center on an ’07 Chevy Silverado with a Duramax LBZ turbo-diesel
Down right bad a-- system. I have an ‘07 Chevy Silverado classic with the LBZ motor. At first I purchased the Edge Evolution. "Only one available at the time." Good product; don’t get me wrong. But then I installed the Six Gun with the in-cab Power PDA. At first I thought it felt about the same until I realized there was one more setting called SL. "Oh Hell Ya!" The next comment I would like to use to describe the feeling it gave me is too graphic and unprofessional. "Holy SSSS"—well, you know. Without any doubt, if you are thinking of the Banks System … Thought Over. The choice is easy: Banks. You guys make a kick a--product. Thank you from Sunny Florida.
