i never would have bought one new and paid full price but i did buy a used for cheap and installed it two summers ago to see what the thing would do. wasnt that impressed with my results. i do like the fact that it kept the fans on alot of the time and the car ran REALLY cool ( a plus to those running u/d pullies ).
since then, coincidental or not, my cars gas mileage has been terrible. i cant check it because my odometer and trip locked up a few years ago. also when under load with the rpms up around 4-4500, i can hear noise and i believe its pinging. i always run high octane in the car.
hypertech claims potientional fuel mileage gains and improved performance. is there any way it could have caused poor mileage and pinging at high rpm? the chip was just taken out so i havent had time to put any miles on it yet without it
also, i hear about 94/95s have some sort of timing retard between shifts that hinders performance somewhat. does it really make that big of a difference? if it does, how can i fix that - bump timing?
