how many of you use it? Im just looking at starting to use tuner cat, and was wondering if its hard to use at all or not?
I know the program is 69, and the definition files are like 20 or somethin like that.

 

also....i have vista, idk if that would cause any problems or not

 

it is easy to use, plus you can use it on a trial basis and only buy the def. file and tune for $20 for the first 30 days,ive installed it into its own folder on my desk top twice now, i will give them there $69 ,but only when im good and ready.there is alot of good info on here on it.ive been able to do everything ive needed just finding info on here.deff worth $20

 

also, my next question, i have a guy that does datalogs for me and then emails them to me, but i will be programming from my desktop, Do you know if you're limited to only one computer, or can u install it on multiple computers once u purchase it?
