Hi all --
After installing a K&N 77 cold air intake and a Flowmaster Outlaw muffler, my 2021 RAM 1500 5.6l/V8 gives me wrong mpg and range readings:
- Before install: 19 mpg over the past 7,000 miles, 450 miles range (mostly highway and with the 33 gallon tank). I confirmed that these numbers are correct by counting miles when I gas up.
- After install: 13 mpg, 300 miles range
I had the battery disconnected before the install, assuming the computer would automatically reset and calibrate.
Any suggested solution?
Thanks!
