Gentleman, I am new to the forum. I just picked up an '09 SS a couple weeks ago, sweet ride. Has only 35K miles on it. Anyway, I am looking to give her some extra ponies and increase the fuel economy. I was looking at other posts and noticed a few guys are recommending the predator or superchips handhelds. I see the DiabloSport predator has been upgraded to the "inTune" handheld. Has anyone has any experience with this? My main goal is to give it some extra horses and increase the fuel mileage - and be able to switch it back to stock when I take it in for service work!!! (I bought the 4 year premium package warranty through GMAC when I bought the SS). So I what I really need is to be able to switch back to stock with a couple minutes of work so I do not void the warranty.
