NEW Diesel owner with questions
 

My father is buying an '05 Crew Cab Long Box 4x4 LT and he wants to get the best bang for the buck performance out of it. Does anyone that isn't a dealer on this forum assist with EFI live tuning? He doesn't know enough to buy a hand held unit and tweak things himself, but would be willing to pay for an extra:tu: license and the time of someone to help him tune the truck. I will also be buying a duramax soon (as soon as I sell my navigator), and would like to do the same thing. Thanks ahead of time. He is located in Jefferson, WI, but would be willing to drive to get it tuned. Thanks!

theres a few dealers on the forum who offer custom tuning with efi live.

im looking @the new 2011 duramax 3500 dually. hows the new additive good and bad. also how much is it to fill the additive tank and where can you get it????
