Well Im really interested in a water meth kit for my cummins but i dont know if it is right for me. I like the snow kits but and i like how the stage 3 kit {not the mpg max} comes with the guage/ controller. but it is also cheaper for the stage 2 kit without the controller. Ive been doing some research but does the controller give you the option to in a way have 2 seperate tunes type operations with stage 3 kit? Also how long does a typical tank of meth last.. 2 quart reservoir.

i also want to run smarty and some RV275 injectors on top of this good or bad idea

just looking for max mileage that i can get without completely breaking the bank
