I'm getting ready to install a boost gauge and wanted some advise.
Should I install a "boost only" gauge on the positve side of the turbo?
Should I install a vacuum/boost gauge into the manifold?

Definitely want it into the manifold - that's the best way to spot for boost problems when they arise. Plus, not sure tubing would like the temps from a turbo's hot side. Vacuum is very important to monitor as well.

Ima get one too.
But what's the difference on those connections?

The postive side of the turbo will read plus or pressure all the time, the maniflod will range from vacuum to pressure/boast

There is a cool spot right after the intercooler that you could tap into...

Yeah but that boost isn't always what the motor sees. Definitely use the manifold for this application. Whether you want vac or not is up to you, but I would highly advise it.

It's "boost" not "boast." Unless you are trying to gauge how much your car is bragging.

Thanks as it was a long day, however, with Iebach springs, Carbon fiber cool air intake, Magnaflow cat back exhaust, tinted windows, all on a
2012 R-line, it could be "boast"...

Thanks for all the feedback, I looked over some vidoes on Youtube of different boost gauges placement and operation, along with your input, I've decided to go with the vacuum/boost gauge.

Well I just received the boost gauge in the mail. I decided on a 30vac/20psi gauge. Also to make the installation a bit easier I found an adapter kit that mounts inline with the PCV valve, and guess what all the lines/hose for the adapter and gauge are the same size. I hope to have it mounted and hooked up this weekend.
Have a great Thanksgiving...

That adapter makes install pretty easy... let us know when it's installed.
I'm not sure about the TSI, but on my FSI I've seen the boost run as high as 25PSI after a chip.

20 sure be plenty as mine will top out about 12 psi

Installed the boost gauge over the weekend. It looks and it works great. I mounted it on the dash between the sterring wheel and light switch. :)
