  • Is the PLX M-300 still being made?

  • "your dumb" ?

    what about it, i haven't done anything with it.

    faggot.

  • and your a dumb nigger... get off of youtube

  • your an idiot..

  • go back to playing need for speed

  • But 13:1 is more power because it is leaner. You just have to be safe and not go too lean.

  • Well 12.5:1 is close to 13:1 but I would not go past that at wide open throttle naturally aspirated. I would not go past 12:1 for nitrous or blower. At idle and cruise your AFR should be closest to 14.7:1

  • I thought most people aim towards an a/f ratio of like 13? or somewhere in between?

  • both. You don't want to go too lean or rich because you will ruin your motor. However, you can use wideband to tune for performance. Having it as lean as safely possible will yield more power. Should be about 11.5:1 A/F ratio for forced induction and 12.5:1 for N/A but those are general numbers.

  • I dont get it.. does the wideband 02 sensor help in your performance? or is it just to better monitor your air/ fuel ratio? or both?
