Hi to all members

New to this site.My question is that I have 2004 crew cab with the 8.1 litre. The only mod that I done to save on fuel is programing.So I'am getting a instant read out of 17-20L per 100Km averaging about 450Km on a tank.Not sure what that would be in miles.Is there any mods to inprove this more?

Thanks For All Your Help

To get better MPG with a 8.1L, your going to have to park it, they by nature get horrible fuel efficency

- "Reduced Acceleration, Drive with Care" message for Valve Body malfunction
  
  By sigmonster · Posted 11 minutes ago
  
  2024 2500 gasser with 47,000 miles. Driving on interstate Friday when my truck shudders, downshifts, and I get the above message with check engine light. Transmission would not upshift. I had to drive home 2 hours at 65 mph at 3600 RPM with transmission temps 190-200 degrees. Got it to the dealer Monday. They ran the code and said the #1 valve body was malfunctioning in the transmission. Miraculously, they had the part in stock and I had a new valve body installed that day with new transmission fluid/filter. Thankfully, all under warranty. Shout out to Everett Chevrolet in Hickory, NC.

  My truck rarely sees a dusty, dirt road, if ever. Actually, never. Within 6mo of ownership, mine was totally covered with road dust and yellow, Louisiana pine pollen. I swear, it looks 6yrs old. You'd think it was an oilfield, or pipeline service truck. Did GM just do a piss poor job of sealing the bay? Anyone else with this issue?

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
