Wow very interesting how is no tune required. Some tuner say the stock fuel system is on verge of being to lean.
The TH does have a better in tank fuel system then a Hellcat does. They tested it at minus density altitude conditions to find what the extreme amount of boost added would be. Going from low elevation to high elevation, to minus DA areas are adjusted by the factory tune. I could not see how Mopar could make a vehicle at the extreme edge of running out of fuel from the factory without consideration for variations in air density.
