    I put it about an inch distal to the merge point of the 3 pieces on the exhaust manifold.
    You installed a fuel pump upgrade for the 2.85 pulley? I wasn't sure what you were trying to say

    It was supposed to say 2.85 pulley, and the URD upgraded fuel pump.

    Nice. Were you having fuel delivery issues or were you just taking precautions?

    Seem to be running super lean. Basically stay at about 22.4 on the afr gauge unless it's under boost. Not sure where he put the bung. I'll find out later today

    what? that doesn't make sense. Your AFR gauge is saying you are running at 22.4?

    I put this in another thread but thought it applies to you
    I assumed the 22 was actually your vacuum line and you misinterpreted the gauge. That number is pure air basically.
    Test the gauge first like the youtube video. if it doesn't work then either your sensor or the wiring. Make sure you tapped into
    the correct fused line.

    Do you get an almost steady reading at 22.4? Check the manual for your innovate AFR gauge and do the calibration process.

    Check where is you bung. Those sensors doesn't realy appreciate being to far from the moter.

    I see 14 on your boost gauge!

    Maybe it's normal to have an AFR of 22.4 at 14 psi of boost lol.

    Using the torque app and a bluetooth obd plug in, I can measure by afr via the o2 sensors. However I find that at WOT the stock o2 sensor wont read below 12.80. I'm pretty sure its getting below 12.80 but I cant prove that. It seems to hit 12.80 HARD and not go anywhere from there till I let up on it. Is that why you guys install wide band afr sensors? The stock 02 sensor doesn't cover enough ground? sorry for the noob question
