I was wondering, once you buy and use a tuner do you still need it or can you just tune your cpu once and then get rid of the tuner?

and if tuners are pretty much a one time deal, anyone wanna sell me one for a good deal? lol or be a good fellow 6er and let me borrow theirs?

tuners may only be used on one car application, you cannot share them...

 

Yes the tuner can only be used on one car at a time, and also, it's very handy to have when the check engine light suddenly trips, or you notice somthing weird with the car.
