Holley Sniper

David, thanks the update.
I hope it works out for you as well as it has done for me. Mine isn't perfect, I occasionally get a stall when pulling away from stop during warm-up if I open the throttle quickly, but that's about it. I've left the programming completely alone ie it's all self-learnt. Maybe a few goes at more throttle from standstill while it warms up will nudge it to learn more in that particular TPS/MAP/CTS/oxygen sensor combination? Or maybe I've got an air or exhaust leak somewhere? Must admit I've never bothered with any data-logging with it.
Also my (Holley in-tank) fuel pump is noisy, even with a full tank. But at least I know it's working!
