My question to you is, do you have the XF-3 or the X-3. There's a difference in the two tuners, the XF-3 comes pre-loaded with three canned tune files. And the X-3 is used for custom tuning, both are capeable of data-logging and reading codes. Both have user adjustability, and if you don't have tuning experience leave that turned off. Both will store three custom tune files, and will store your stock tune file. But only one will do true dyno custom tuning, and that's the SCT X-3. So depending on which one you have, or would like to purchase depends on the gains you will get from it, Mike. SCT Tuner.

70 BOSS,with a 71 429 SCJ 8.0:1 compression with an F-3 Pro Charger and 39lbs. of boost. Rectangular Tube Chassis, Custom 17" Magnum 500 Wheels. Just way too much to list, but what a ride. P.S. Hang on tight!!!
