Check Ebay -- I got a used Diablosport Predator for $250 shipped. But make VERY SURE (ask!) that you are getting a unit that is not "married" to a car. Only buy from someone with a proven feedback rating and make sure you use Paypal so you have some recourse, "just in case".green 01 said:boo... i didnt really want to get one. but what tuner is i little cheaper but will still work for what i need?
