Yeah you dont want an M7 anything! I have one of their intercoolers, and it is junk! Even with the big hole cut into the hood behind it, it would heatsoak badly and take FOREVER to recover. Being in Vegas I can tell you it would be way worse than it was here in Denver. I wouldnt even do the GP-I/C the benefits of that are minimal at best, but it is a better option. Best thing you could do (and it is in the same price range of those two... $800-$1000) is get a meth injection kit. Assuming you can do the install which isnt horrible, but if a shop does the work labor will be pretty high.
