Was wondering what tuner would be best for mileage for a 07.5 lmm on 35s. Something that not a pain for the crappy state a live in. Thought about running a eco tube thru efi but I’m not sure about the smog I Cali. So trying to see different options for a tuner

I had the canned PPE Hot+2 Xcelerator Race version on my 2007.5 LMM with 280k miles, truck was a crew cab short bed leveled on 33s and it would get 20 to 22 mpg going down the highway. Better fuel economy than my LML. You could find one of these tuners pretty cheap second hand now as well.
