Don't believe brenspeed does work for the Diablosport. Bamachips does DS tunes for sure. I believe it's 1 for $50 or 3 for $100. You basically tell them what your mods are and what octane and type you want they make it for you, you upload to tuner then upload to car. I have one for my C&L Racer intake however i use the canned tune which sucks i'm waiting until i have CMDP's until i get a new tune.

Edit: Yes the tuner locks itself to your particular car when a tune is loaded onto it so it can't be used with anyone else's car. However when the stock tune is loaded back onto the car it is unlocked from the car and able to be used on anyone else's car.
