Message I believe I *might* have figured this out but I want to get some other peoples oppinions before I proceed only to disappoint myself.

My TT has a NA rearend (complete, no hicas). My speedo is incorrect, I believe it registers slightly higher than I'm going. As I understand it, I need to swap my TT's transmission speed sensor to a NA sensor and that should fix it. I've recently seen a few wheel speed sensors in the classifieds and I'm trying to figure out where the information they give goes and if it has anything to do with my problem.

I also recently got the Blazt software and hooked it up, only to find out it was reading a different mph rating than my speedo. 38mph was around 46 (If I remember correctly).

So the question is... what do I replace or adjust to make my speedo read correctly? Where does the information from the wheel speed sensors get processed and then what gets influenced by that information?

Thanks everyone!

The beatings will continue until morale improves.
