Hey all. So I've read several threads about tuners and I'm curious. Have any of you added the tuner after the car had 5k miles on it? Reason I ask, is my car is completely different then before 4k. The throttle response is much better, the shift points are better, same things y'all describe with the tuner. Did it make the big driveability difference as I keep reading about?
Thanks,
