Also swap out the fuel tank, and drill a hole and use the second chamber of the pipe for pressure. Hold on to that NTC3 fuse, it will walk all over the belt cars.
I agree......there have been THOUSANDS of Tc3's sold...the original gas tank(Chicken hopper design) could have been a problem with tuning(same as it couyld have been on the GT for the past 10 years)....and to be honest,there were more people who NEVER had a problem with that tank on the tc3,than did...
the new top feed tank solves the EASE of tuning issue....
Maybe the pipe that comes with the rear exhaust makes it a little harder to tune,but I personally don't see a problem with teh car at all....
BTW<if the car is thermally challenged,how does putting an exhaust pipe half of an inch from the air cleaner help?....
but I'll bet there are more people who cant tune a NOVA style engine than there are problems with teh car..
