Honestly id avoid the Diablo. Its fine and all but doesn't offer trans support. And Kinda crappy customer service. One GXP owner has both the Diablo and the new superchips programer. His plan was to compare both once diablo got all there updates. Well i think its been close to a year and he has given up and selling it because of lack of suport and crappy customer support. As far as cams. Yes and no. Most any cam for a LSX will work. But if your keeping DOD you cant go to big with the cam. There have been a couple guys swap cams. However they have ran into some issues. One of them is if the cam moves the power band higher, then while racing when you shift 1-2 you could possible be completely out of the Power band. There are some other things that if u really want to go ahead with the swap ill get the info straight and get it for you.
