anyone use Shiftmaster tuner
 

Has anyone ever used shiftmasters EEC-tuner? It is the one you can hook up to your computer and reprogram. What do you think of it?

I have really heard nothing but bad things about the software, get a Tweecer or a PMS unit you will be a lot happier when you start making changes.

I have the EEC Tuner right now. I havent used it yet as I am waiting for the software for XP to be developed and debugged. As it is right now it is very hit and miss (mostly miss) when using XP.
