I' ve got a C&L cold air kit with a diablo tuner on my 05 GT. I've seen other post talking about breenspeed tunes. What's the difference from what I have? I'm new to all this!
Some custom tune shops use SCT-X-cal, other use Superchips and others use Predator. They perform the same functions; the manufacturer of the tuning device is the difference, along with the functions the handheld tuner can perform.
