Yes, simple adjustment on the mixture screw with an allen (6mm, or is it 4mm....whatever, you'll figure it out). Push down the adjustment plunger until you feel resistance while turning it. Clockwise to enrichen, but don't turn it more than a couple degrees at a time.

Your wide band sensor - mounted 18 degrees from the turbo - must be in the muffler tailpipe, correct? If it's too close to the end of the pipe, you will see an erroneous lean mixture 'cause it's seeing ambient air. If that's not your location, then a simple mixture adjustment will do you just fine.

This thing about your "hicckups" at idle, and hearing the fuel pump relays click. Damn, you can actually hear those things? They should not be clicking randomly. That's weird. More descriptions, please.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
