Hello, i'm wondering if anyone is using a hand held tuner for their coupe. I personally have always used one on my LSx powered GM cars with great results, until I went big and did a dyno tune.

Which brand and unit do you use? (include part #)
which is the most popular with the best results? (focus is on the A5 tranny)
Where can I find the best prices on one?

Thank you for your time

 

no one?

 

Like everyone else is going to say Orisis is the best tune for our cars if you have the availability to due it. Personally I am saving up for a unichip...
