Get an SCT. I picked my Livewire up on ebay for $200 used. That's right, $200. :smilie X3/SF3 would work just fine as well. Most of your major tune shops use the SCT software.i need to buy a tuner whats better diablo or sct help please!
The Street CAI also requires a tune. However, the "tuneless" version of the Street CAI with the insert does not need a tune.If its the Racer intake that requires a tune it will throw codes and go into limp mode.
