My friend just ordered a Hypertech Programmer III for a great price for his 05 Silverado Crew Cab 5.3 V8. Anyone have any reports on this programmer?
:word: COMPLETE waste of money bro :imoTell him to cut his loses and put it on ebay. They're crap.
He should have spent his $300 or $200 or whatever they cost on a custom tune from BlackBear Performance. They're a sponsor on here and just about any performance website.
