Hey guys, just curious about engine code reflashes. I saw in the engine section all the hype about getting the reflash done. Do these updates apply to the Duramax medium duty also or just the light duty trucks?

kodiak 03-08-2006, 10:22 AM I went to the dealer to have injector harness work done. They said that there were 4 different updates for my 05 Kodiak. One of them was for turbo bark and another was for a speedo calibration, and I don't remember the other two. Other than the bark, I can tell no differance. dmaxtechreno1 03-13-2006, 11:40 PM got good news for you med duty guys gm has a update available for cust wishing an upgrade. they can reprogram the ecm to give you an output increase. ill do some research on specifics and post it asap. tmcblane 03-16-2006, 10:01 PM Sweet news Dmax! Keep us informed!:cool2::cool2: dmaxtechreno1 03-23-2006, 08:26 PM Those Of You Wishing To Upgrade Contact You Dealer And Ask Them About The Vci Program Update For More Power As Far As I Can Tell I Is Something Youll Have To Pay For And Im Unsure Of The Amount But It Is Available. If Your Dealer Is Unaware Of The Program You Can Call The 1 800 # For Gm Cust Assist And Ask They Can Help You As Well. Good Luck And Happy Motoring. rht141 03-23-2006, 08:55 PM Does this Vci apply to the 2006 4500 w/ 300 hp? dmaxtechreno1 03-23-2006, 10:02 PM Does this Vci apply to the 2006 4500 w/ 300 hp? im still searching for more info ill post for ya asap. Dirt Dog 03-24-2006, 12:08 AM I think the recent announcment you heard about is for the 7800 Duramax. GMICT just announced a horsepower upgrade program for them. There is nothing for the 6600 that I know of. | ||
