As suggested, RomRaider is a great solution and the tactrix is worth the money no matter what you do. Even if you use the Cobb AP the Tactrix can come in very handy for logging high resolution data. You will need to get yourself familiar with it and also ECUFlash as well. The thing I like most about RomRaider is the overwhelming support and a knowledgeable community.

Just one word of warning though. If you have never used it please read up on its use and functions. You can do irreversible damage to your engine if you are unfamiliar with it. Also to be successful you need to have the latest version along with the latest ECU definitions for both RomRaider and ECUFlash.
