Thinking about buying the GMTDScan tech software, I already have the interface cable but was just wondering if the program is worth buying to solve a few small issues and change shift points ect.. Anyone got any experience with it?

 

It is diagnostic software ONLY and is worth having.

A Buddy,Heath,Kennedy or KOJO ECM/chip tune is required for changing shift points.

 

Thanks for the input, I already bought it and it does help tremendously, Im getting ready to tryout the tdc relearn and set the timing on my dads trk tonight.

 

Good to hear.
For 94,95 a Buddy 6 gun tune is the way to go.
