Hmm, surprised to see all of the bad feed back about PTC. I have used & ran them all. Only bad luck I ever had was a 8" TCI got trashed one time on the street. I am on my 4th PTC now.(4 different cars). One has been in my Charger for 10 years or so 10" 3800. Current new convertor is in my Challenger to be tested this summer. It almost always seems like they all have to tighten them or loosen them 500 +/- RPM or so at least once these days???
