I bought a diablo sport predator for my 03 cobra is that hp tune good if you put in an exhuast and a cold air kit i know you can tweek the programmer but is the tune it already has any good?
Not really... Get your exhaust and CAI installed and then order a custom tune and use the Predator to upload the custom tune into your car. The pre-programmed tunes that come with the unit are garbage, some are even downright dangerous!
