I LOVE IT. Its alot more fun to drive, I don't even know what it did. it does shift earlier but who cares. its not like my car is fast, now its just a slow car thats fun to drive. It rockets out of 1st. If my car was turboed or had some more power I think this would be a very worthwile mod.
It was so damn easy too, I just... cut the wire, it was easy to find, I just snipped it and said, what the hell... it was weird for a day or so... but now it rules. What exactly is this doing to my car?!
