Well, about 30k miles ago, i had a no named heavy duty tranny installed. It supposedly has a upgraded VB and TC.

Well, i was in detroit this week and hooked up with bgchrysler. Very nice guy, he was a chrylser engineer for 17 years and went on his own, but still does freelance stuff.

Anywho, i just got a stage 2 custom towning tune for the tranny and let me say what a difference it makes. Anywho, if you have a 68fre, you should check it out.

I have custom tuning in there as well as I tow heavy all the time. But I have stage 2 w/ custom towing tune.

Maybe I will get better mpgs, i dont know, but i know im putting more power to the ground, thats for sure.
