hmmm the how much meth is ran and how it kicks in question is actually a really good one im interested in the answer!
unless he has a stand alone ems then i doubt he is running it full time.
also if it where running full time then the 5 gal would go out on him quick.
the only thing i could think of is its activated when his vtec kicks in *no this isnt a honda joke* that would make the most sense, being as how vtec raises not only timing but compression and just like boost when the hightend compression kicks in thats when he would need a higher octane fuel to not detonate. thats my theory on how he's running his.
but i wanna here it from the horses mouth and see how close i got.
