I installed an Autometer vacuum/boost gauge this weekend.

What kind of readings is everyone getting?

Under "normal" driving conditions, it'll read about 20 in./Hg vacuum.

Under WOT, I'm getting about 6 psi boost.

Please post average readings and if you have any modifications.

Thanks. cool

BTW, my X is entirely stock.

Mine sits at about 18 when warmed up and idling. and I have seen anywhere from 6 to 8 PSI under WOT. No real mods that would effect the SC. With the boost mod, I was seeing in the 9-11 psi range, but it is hard to say for sure if that was actually being produced.

Don't have any pics yet and don't have a host server. However, I'll take some later this week and e-mail them to you.

I placed the gauge on the A-pillar above the tweeter. I used an Autometer mounting cup. While it doesn't look like Ag Bullet's set-up, I like the way it turned out.

I would see 18psi w/ spikes to 21psi @ 5500-rpm and above.

That was in my Eclipse. wink

I can't wait to see what little mods pop up for the X's supercharged engine. I am a big fan of forced induction and the cheap and easy power gains you can get from it.
