Sorry it took so long to reply. I finally sat down and checked the hoses; I could not find anything wrong. So then, I switch to the race tune. It seem to cure the problem. The high reving has stopped, and the throttle response is way more controlled. For some reason it was really touchy with the 93 Performance tune. With the 93 race tune, things seem to be working much better for me. Is it possible for the car to respond differently to the winter gas? Anyway, I will just load the performance tune when inspection time comes. I like the race tune better anyway, and I get a little better gas mileage with it.
