    21.5 lb Pink top injectors on m50 (with tune)

    Is it possible to use 21.5 lb injectors on a m50 that used green top 17 lb injectors. I also have a turner motorsport tune. If so what should I expect out of it.

    are slow.
    Does your tune specify that you use a 21.5lb injector? I'm not aware of any Turner Motorsport tune for an M50 that uses 21.5lb injectors.

    Just tossing in a larger injector is going to make it run rich and not well.

    Im not sure. Probably not. I was just curious because I found some pink top injectors for cheap.

    are 21.5lb injectors going to really support any real boost?

    Sure. But even at 90% duty cycle you can't go above 200whp without going lean. 21.5 injectors are fine for a stock or slightly modified S52, but for forced induction you'll want a much larger injector. 40lbs+.
