Assistance with fuel gauge reading
I purchased my truck from a private owner last year who changed the 26 gallon tank to a Titan 52 gallon. The problem is my fuel gauge still reads with the 26 gallon or close to it. I've tried to use the DIC's by watching the gallons used but found this to be very difficult. I spoke with my local Chevy dealer who advised me that Chevy doesn't have the program to change this. I called Titan and they stated EFI Live or Bully Dog will / can change the gauge and make the DIC read properly. Is this true and if so can anyone assist me with EFI Live? I'm not interested in any tunes, programs, etc. just making my fuel gauge and DIC read correctly.
