trying to help wherever i can.thank you for the great info, I understand it takes a lot of time and effort to give free content to others. With that said, I am curious if you have ever thought of, or heard of anyone doing tunes to the new wrangler eco diesel. I have a 2021 jlu diesel and with steel bumpers, 37's and 4" of lift I get 24.5 hand calc (average for a whole tank, city and freeway in arizona) and stock I got 30.5 hand calc. I am extremely pleased with this but know there is more to get. I drive like you and have a mpg obsession. P.S. I have zero engine mods, just lift tires wheels, bumpers and I use the taser mini for tire size, etc.
the exhaust is a restriction, i like borla and awe personally. I think a minimum of 2.5” diameter is what you should shoot for.Really appreciate what you are doing here! I would love to see you post up some kinda product recommendations list for those of us that are interested in trying to make improvements. I’m thinking about starting with a better filter/airbox now, then maybe tuner, and lastly exhaust only if I have to.
