If I buy this diablo trinity tuner can I switch from economy to performance as many times as I want

 

I don't know a lot about the Diablo, so hopefully someone can back me up or correct me. But I believe you can change tunes as many times as you want. You're only limited on the number of times you can change cars.

 

Yes you can

 

Do youbsuggest that tuner?

 

SCT is more widely used, and will be my personal choice probably later this year for my car.
