    whats IAC % and commanded fuel mass doing at this same time?

    This. So annoying. I've seen it on multiple engines with similar workarounds.

    Carbs and throttle body injection systems are both wet plate designs - making them both susceptible to the same problems of poorly atomized fuel, especially while cold. Fuel atomization doesn't see real gains until you get to port or direct injection.

    How far is "way downstream"?

    Ya got me. I used the wrong name. It trims down at 160, for sure. I was referring to the speed/throttle screw.

    Check your IAC position at cold. Sounds like your initial position set is incorrect.

    These inline pumps get quieter as tank pressure increases since the tank pressure is effectively pushing fuel into the pump. You say yours got even louder, though, so you have something else going on. I don't regret moving to an in-tank at all. I kick myself for dealing with the in-line...

    Gurgling fuel tank is a strong indicator. Given that the system clears itself up after a brief wait it sounds like you're venting too slowly. I'm curious, did the fuel pump get quieter around this same time?

    Tipped it on its corner, soaked up all the liquid, and pointed a little squirrel cage fan at the opening for a half hour. It was dry and fumeless when I got back to it.

    The photo below shows the factory fuel pickup and the tray it lives in. The hole we're talking about drilling is directly above this tray. If you remove the pickup assembly, cap the pick-up mounting hole, and install an in-tank module in the location we're referring to then you are no more...

    Hole has to be drilled if you want to use an in-tank pump. Not a hard task though.

    Interesting. These trucks have the O2s placed just how Holley advised. But, I'll give that a try.

    In the half dozen or so Snipers that I've set up or worked on, not a single one operates like the factory EFI that Holley markets it to be -- even after they've been given the time to learn. I know of three with this dip. One straight up dies until it hits 160F. Another dips and also has a...

    Not much going on in there, T. That's for setting base things like number of cylinders, boosted or NA, etc. It's either right for your engine or it isn't.

    I bet that's an artifact of the math. I bet a log taken during that time would've shown an interaction between injector flow rate / on-time and the indicated fuel pressure.

    I generally agree. The exception being that I'm not a fan of mechanical gages in car interiors. One of those little hoses fails and it's a real problem. High quality sensors can be had for similar money as the mech units and they tie in so well to Sniper's system. It's hard to pass up.

    Without a pressure gage, that number is going to be a math output. Better than nothing, but it's open to too many variables to be relied upon. Sniper does, however, have provisions to add your own fuel pressure sensor. You'll need to calibrate the pressure to the sensed voltage, but it's a...

    Same goes for pant makers... slacks and jeans bought on the same day and fit the same have 2 inches difference in the label. Seems like a good opportunity for ISO involvement.

    I'm all over this Holley option. Looks great and I'll get to scratch my nerd itch with some ECM tuning. I haven't seen anyone speak about fuel economy yet, though. Is it better? Worse? Or is it a push?
