Prob no average, make as much as you want-but I would say double what it is NA as an average.
Bad side could be costs if you don't have fab skills
Meth wont bump up the HP like nitrous, it allows some safety in tuning for more HP

Are you referring to running meth as your primary fuel or as supplemental injection like the title states?

It doesn't add HP. It allows you to run more boost/timing safely. It should be used as a fail-safe, not a primary fuel source. What I mean is have adequate afr on your pump gas tune first then the meth is the added security blanket. If you tune full bore with the meth kit and for some reason it fails you'll be looking thru your pistons
