I just purchased a 03 2500 and got the latest version #3 of Hypertech's top controler negotiated into the sale. 30-60 and 90 hp gains, and even more torque. I trying to raise some cash to buy a new BD brake. Just make me a fair offer. Less than a year old. Make me an honest offer. New was, and is 369. Just drop me an e-mail before I put it on E-bay this Sunday night.
