Hi I own a 2000 Mustang Gt and I plan on adding some stuff to my car (CAI, High performance spark plugs and coils, and long tubes) This setup will require a tune for my car to run right but here is the problem. I plan on supercharging my car in about 7 months and I will have to throw the car on a dyno. The question is can I download the dyno tune to the handheld tuner so I can keep modifying my car or will i just have to throw the car on the dyno everytime I do something after the supercharger goes on.

IMO you should read some of the recent threads regarding the EPA suing the makers of hand held tuners that allow the end user to defeat SMOG controls. It's a big deal.

Regardless you should find out WHICH tuning system that YOUR tuner is using. Use the same system.
