Was going to head to get a dyno tune next week but i gave the dyno guy a list of mods and he wanted to know if i was running a ProM or Pmas MAF...Well im an idiot and dont know lol. After not finding anything on the sensor its self im guessing that i have an aftermarket housing with a stock sensor in it? Sooo where do i go from here? Do i buy an all new housing and ProM or Pmas Sensor? Or is there a place i can buy a ProM or Pmas sensor for my C&L housing?
