Tuner needed for my Cobra

That won't work. A hand held tuner like a Predator or xCal2 are "married" to the car, sSo you can't share one between vehicles. You will need to go and purchase one brand new for yourself. Ask your tuner what software they use at their shop for tuning and then purchase the appropriate handheld. If they tell you they are just going to use the handheld by itself to tune your car and won't be building you a "custom" tune and then using your handheld as a delivery device... FIND ANOTHER DYNO/TUNER SHOP!
