Steve-Maine Posted May 28, 2013 Posted May 28, 2013 I have a 06 GMC 2500Hd with duramax and alison auto. I'm thinking on putting a performance program in truck. I talked to one garagre that recommended a Hypertech Programer. It was $389 installed. Is this a good programer for hauling a trailer with antique car. Enclosed trailer weight with car would be about 7000 lbs. Thanks for any help..
