Never found anyone who could show records about mpg using Smarty, but near universal that it's the least damaging tune. Trucks with auto trans suffer reduced life of that component. Same for injectors.

If one CAC system boot is bad, they all are. Having lasted that long they're due for replacement.

MOPAR 4" paper air filter the one to have.

Glad mysteries are receding.

Exhaust brake great for 10k pound trailers. Not really otherwise. I'd still do repair.
