    MAF size vs. Injector size

    Guest-only advertisement. Register or Log In now!
    I recently installed a GT2X turbo and am running pc-16 tuning,
    i installed 440cc injectors and have heard of people running bigger MAF's w/ bigger injectors on pc16 tuning with the GT2X. iirc you should increase MAF size the same percentage as you increased fuel injector size to maintain the same AFR. Does anyone have any experience running a GT2X with the pc-16 tuning?


    thanks!

    i've heard people doing that with a success. its mostly 1.8t vws that are a bit lemmi tweaked. Now that there is an fueling piggy back diagram, you should take advantage of that.
