Thank you so much for the help. I am kinda leaning towards the Diablo now. I sell Hypertech where I work but with the overwhelming of Diablo makes me very interested in it. But with those answers I have another question that pops into my head. What is the catch cans main benefits and what is the purpose of it exactly? Also what other mods would be a good recommendation being as I have about another 8 months before I can work on it again since I am deployed to Afghanistan at this moment in time. I have already done the Airaid MXP intake system, I have also got on it a Bedrug, Access Cover, 2-12" Access LED Bedlights, TAG Truck Luggage, Access EZ Retreiver II, DeeZee EZ-Down, Putco Plasma LED Reverse Lights, PIAA Headlights and Fog Lights, Putco G3 Dayliners, and WeatherTech Front and Rear Floor Liners. Im looking at going with Magnaflow cat-back exhaust and the Diablo tuner(now). Any suggestions would be awesome. Thanks all
