Main concern: Driveability
Wondering if stepping up to TR7IX's would be worth the money. Right now I have a stalling issue, sometimes choppy idle, and sometimes choppy cruising speed. I have the TR6's installed and only have about 2 or 3k on them. I had a set of TR7IX's but my tuner said not to put them in. He basically said he has seen dyno runs where the porcelain cracked or blew out of every plug.
Has anyone had experience with NGK TR7IX's cracking or basically destroying themselves inside the head?? I have heard many people say that idle GREATLY improves with the TR7IX's, just sucks that my tuner said to stay away. And at the time I trusted the tuner, Dan at Pro Dyno.
