    S1 w/s1 injectors and basic bolt-ons. SAFC is zero'd all the way across the maps.

    17psi spike on stock turbo... stock fuel besides a fuel pump rewire and Walbro 255.

    At initial WOT AFR's are in the 10's.... towards and by redline it sits at 11.0-11.1.

    I would of thought it be richer in the low 10's throughout the band as in the past thats where it was. This was just a few weeks back when I did the fuel pump rewire.

    Recently changed:
    AGP wga for a FM (Forward Motion) wga
    Autometer Wideband back to my AEM Uego Wideband
    Took out the K&N SRI and put the stock intake tube with filter on the end

    I know the AFR's are safe but for it to be leaning out to 11.0-11.1 at just 17psi didn't seem right to me.

    0 knock and when I glanced at timing at WOT it went from 19.0 to 23.5 (didn't check where it was by redline).

    Any help/input is always much appreciated.

    yea that sounds about right. the stock fuel system is much more limiting than people think it is

    Might be a good idea to get a fuel injector cleaning done to your car. A ton of shops have them.
