I have a 2008 GMC 1500 Pick up 4 wheel drive I bought brand new in 2008. I am thinking of putting a simple easy programmer to improve performance. It has the stock single exhaust and I will be upgrading to dual exhaust. What would you recommend in the Diablo line of products. This truck does have the engine that when I am cruising will drop the 8 cylinder's to run on 4 cylinders to save on fuel consumption. Its also equipped to run on flex fuel and I live in Alaska which have cold winters at times. I stays out side but its also low miles. I tried to search on Diablo's web site but it came back as NO products available for my 5.3 engine. Just looking for one that plugs and play. Cost does not matter for me just as long as its easy to use. Thank you GS
