It's been a long day.

But,at the end of it, I've installed a calibrated boost guage, an air/fuel LED meter and a TurboSmart Manual Gated Boost Controller on the A-Pillar (the boost controller is still under the hood..unfortunately :>)

Everything is working as it should except for the A/F meter. It's got a semi-circle of LED bars that run from lean to rich, left to right. I grounded the meter electrics to the intake manifold, black wire ground closest to the firewall. The directions are very adamnant about using a "GOOD ENGINE GROUND".
Not the body or under the dash somewhere. Would the intake mani not be an engine ground? The LED kinda whips back and forth, sometimes sitting still on the rich side and not even registering any LED's when the pedal goes down.

The "Directions" have a small trouble shooting section, ahem, paragraph I should say. They caution you against all the times where the guage might read oddly, due to deceleration, warm-up, etc., but this isn't in there.

When the O2 sensor is metered by a digital MM, it seems to act normal, jumping from .2 to .8 v or in between. The sensor wire coming from the guage was just sandwiched in between the spade halves. Was that not very professional nor smart?

The diagram shows the attachment on the wire itself, on the computer connector side, versus my quick trick. Once again, does anyone think that was a dumb thing to do?

other than the disco party, I turned it up about 1 psi, after some 92/93 octane gas......man, was that fun!! It seem to spool up quicker, something that TurboSmart seems to say will happen on their website. The site is worth a look, very slick products that win awards. Mine came off a car that it was on for 2, yes 2 days, before some youngster turned it up too far. The indie shop said it's fine, gave me a deal on it and promised a full warranty. It "clicks" as it's turned, so you know that 11 clicks is one revolution, suposedly equal to 1.25 psi. Comes in handy when you can't see the dial face. I've noticed a little more whistling coming from the engine compartment, I'm hoping it's the bleed hole on the boost controller. Really hoping. Is that a usual thing?

Thanks in advance for any help, opinions or general banter.
