I have an 05 GT with the 5 speed manual trans and I am looking for advice on the best device to buy to tune for 93 Octane. I have not made any mods to the car. With my stock tune I have recently been running 91 octane since I had a sensation of detonation with the regular gas.

I'd like advice on the best device to buy so I can get some power increase running 93 octane. When the car is out of warranty I will add a CAI.

Which device is best to buy for now to run 93 octane and will also handle a tune for the CAI afer 36K miles when I add the CAI?
