I've had my PTC NA now for about 2 months and so far I'm happy with it
, the initial stages looked questionable
After basically tearing the entire front end apart and rebuilding it, and some rear end work I'm glad I have it, the gas mileage while not perfect is far better than what I came out of.
One thing I have noticed though If I drive while in city traffic in 3rd it performs very well, and there appears to be no apparent loss of fuel mileage.
After doing a exhaust and new intake it woke up quite a bit, no its not going to win any races but I'm happy with it now.....
