Does not work with my car
I bought the stage1 because I thought having a K&N typhoon intake system and a Jet MAF sensor would be considered a minor modification, but when installed my car hesitates, cuts in and out and stalls! I am going to try exchanging for the stage 2 and see how that works! I've tried asking JET themselves but they won't answer me back!! So make sure if you buy the stage 1 your vehicle is stock!!
Couldn't really tell any difference on 87 octane but it did seem to come alive a bit on 93. Throttle response is definitely quicker though. I'd probably buy again just because I've heard bad things about the more expensive units on the market. Don't really think it helps gas mileage either. I do however have a CAI on the way & put exhaust on last month so we'll see how all the mods work together.
