If you plan on doing any kind of tuning now or in the future, it would be a good idea to go ahead and get your ECU chipped. Either you or your tuner will be able to change your fuel and ignition maps as well as setup your full throttle launch aka "2 step".

Like Schmoo was saying: Uber and Crome are examples of the software which will be used to edit and make changes to the maps and add whatever other functions you want.

The burner is what actually "writes" the changes to the chip and the wideband is a tool to help you tune it (If you're going to do it yourself.)

If you're serious about it go to wwwPGMFI.org ,if all you want is a 2 step get a MSD
