Does anyone know if you can upload your own custom program onto a Hypertech power programmer 3. I know that it stores your vehicles stock program into it when you run their custom settings. So why could'nt you trick it into storing a custom program you create instead of the factory one? I'm just curious of uses for these things, cause I picked one up for $10 at a garage sale.

 

Your not going to be able to use it on a thirdgen anyway so might as well sell it on eBay and use the money toward other DIY PROM goodies.

 

if there was no lt1 swap or anything done then yes it would be usless
