'03 Boost Gauge Install

[Parshal]

I just got my gauge today and I'm looking at the enclosed instructions from Geno's. I'm trying to figure out where to drill for the boost gauge as the '03's look nothing like the drawing. Where did you guys drill? A picture would be worth a 1000 words here, I think.

Do the Piers Boost Bolt. No drilling necessary.

I was thinking about that, too. I looked at the website but how exactly does that work?

You remove one of the short bolts (an inboard bolt, towards the head) on the top of the intake manifold and replace it with the fitting. The boost hose attaches to it. No fuss, no muss, it's what I did too.

Does it provide the exact same reading as a drilled/tapped fitting?

 

[Greg Boardman-RIP]

It provides intake manifold pressure/ boost.

Yes, reading is just as accurate. Like David said, no fuss.
