I have a 2003 SVT Lightning and I want to get a Diablosport Predator programmer and change my upper pulley to a 2.75". I bought my truck used back in June and I think it has a tune on it already because the shifts throw me back in my seat. How do I find out whether or not my truck has a tune on it? If it does how much does Ford charge for a reflash? Thanks.

 

Not sure about the if you have a tune part but the dealer is about 1 hours labor to reflash, hopefully you wont have to leave the truck with them..
