Very pleased. Plug in, turn truck on and that is all it takes. Shuts off AFM. No oil blow by and usage because of v4 mode. Have a custom cat back. Drone when in v4 mode is annoying. Range eliminates this issue. Got 19-23MPG during a 400 mile trip through rolling hills with my 5.3L engine usig Range. Not bad. Have had no codes. Removed when has truck serviced. No warranty issues.
