Autometer normally makes very good gauges. This one is particularly well made. You have to pull a vacuum line all the way from your dashboard (or gauge pod) to your turbo which can be problematic. The vacuum line supplied with the gauge is a joke. It thin and would bent while you pull it. Or melt if it would be touching your engine. I have enclosed the line into a rubber tubing to keep it safe. You can grab such tubing in any Home Depot or OSH. Also I advise to use bigger diameter T-fitting for connecting to the turbo control valve. But when it's all done and working you'll be happy :-).Note that the is a flaw in some of the boost gauges. It can rattle (or shake) on low engine RPM. This is very annoying. I had to change a few of boost gauge until I found one which does not do this and keep steady though the whole RPM range.

Looks great and works great showing my boost. Picked it as it fit well with my car's interior. Nuff said :)

Great gauge. Works very well. Needle is a touch off center like in the stock image in this listing, but doesn't effect accuracy. Does its job and I would purchase again if needed.
