Which Shifting is Best?
Okay, so I'm bout to order some tunes from Innovative, but I'm curious: Which shifting is best for the life and the longevity of the tranny? Mine could be on it's way out, but I want it to last as long as possible.
I have tuning from Vivian now, and the Looney Wild seems to "suck back" when shifting, which I think is defueling, and I've heard that's bad news for the 5R. Needless to say, I'm on the stock tune for now.
The reason I ask this is because on Innovative's website they have different options for shifting, and I'm not sure if the Firm Shifts will be better or not.
