My father has a 2004 LLY Duramax. We pull a pretty large boat, my car sometimes to shows/races and he is looking for a programmer to help it along with some better mileage and power. If anyone has a programmer he/she would like to sell please let me know. His birthday is coming up soon and I would like to get him one if I can afford it. Thanks

Hypertech 30029

If you're interested I have a Hypertech Power Programmer 30029 for 01-05 LLY duramax. It will not work on my truck anymore because I had the computer updated and now my truck doesn't recognize the programmer. If interested, make me an offer.
