Gm stage 3
Strongly disagree with that. The most ideal thing to do is to get 60# injectors with a 2.8" and all the required supporting mods cooling, exhaust etc. If a good tuner is not an option in your area then the stage 3 could be the best choice for you especially if you plan on getting nitrous. If you must get the 60's and everything in a canned tune I would say to go with OTP definitely not Cobalt addiction I haven't heard anything good about those kits.
It really just depends on the dealer, they are not suppose to warranty the car once the car has the kit on. But I have heard that a lot of dealers will still warranty the car if anything goes wrong, as long as you pay that specific dealer to install the kit.... even the nitrous.
How much would a dealer install on a Stage 3 be on a stock 07 if they can indeed keep it under warranty. I originally planned on this car being an 4 seasons driver, but after last winter I'm not chancing it again. I figure the engine mods are better for the car than snow! So I'm trying to figure the cost of Stage 2 vs Stage 3 + the cooling mods that'll need to be done to support stage 3 (methynol injection). Any info anyone can come up with would be awesome.
