I'm having a hard time tuning the idle on my 168. For the time being, I fabbed an adapter plate so I could bolt on any other TB. When I come across new data for the 168, I plan on continuing my attempt to get some driveability with it... But if I cannot get it to where I want, I will be selling it.
I tune myself and I also know that Lund can tune this TB, but is never willing to share what he knows about it. Therefore, I must resort to other sources. I have several, just no time to tinker.
