i guess is what im trying to decide is , i am only running 8 psi and i dont really plan on goin more for a long time yet so would geting MS actually do much for me or no? i would like to get it but im confused at this point on how exactly it takes place of stock ecu , like what about speedometer and everything else the ecu controls. and im not even sure of what version or components i would need. im reading posts on here but i dunno..
