alright i'm about to buy a water/meth kit from a friend and want to buy a boost controler, but i am wondering how much boost is too much?? as of now my mazdaspeed 6 is stock so if anyone can let me know how much is too much psi to be at. im thinking about running about 20 once i get the parts but would like to get up to the mid 20's once i get a few more parts for it. do you guys think this is a reasonable amount of boost or am i just way out of my ball park??
