Vacuum and Boost Questions!
Hey guys,
I finally installed my boost gauge yesterday after getting everything I needed for the install. I'm really happy with the results, but I have a couple questions so I can verify that the readings that I'm getting are accurate. I have the Procede v1.47 currently installed and UR catted DPs. At idle, I'm getting 18 In Hg. At full boost I'm getting 12ish PSI. I'm at sea level. Could you please provide the following for me so I can compare the numbers to make sure that there are no leaks with mine? Please have the reaidngs be CURRENT. - Tuner program - Exhaust - In Hg at idle - Peak boost - Your elevation Please don't turn this in to a pissing contest; like...Oh yah, well I peak at 20 psi all the time bla bla bla. Thanks a bunch! Here are the final pics.

Looks good! Did you actually screw it down, or just sit it up there with that bracket?

Did you or can you print up a DIY? That looks pretty darn good. What gauge is it and how much did you pay for it?

This is an STRI gauge. I posted this poll regarding the placement, but I think that a lot of people had problems with how I was going to mount it. http://www.e90post.com/forums/showthread.php?t=104461

I have a feeling that the pressure fitting that came with the original vacuum line didn't fit a tight seal with the new black line that I got.

Looking good! What is holding the 'Gauge' in the lower Exhaust Flange?
Thanks, Dave

In post 4 you'll see a link. We talked about most of what you PM'd me about in that link. The exhaust flange I got at Autozone. The gauge I got from here: http://www.ravspeconline.com/shop/ca...oducts_id=1724 As far a s a DIY, I'm too lazy right now. Maybe later.

I have a feeling the pressure fitting was too big for the vacuum line. What mods do you have?

I just wanted to make sure that it sealed correctly. I know there's no flow, and as far as hearing hissing, I don't know if I would be able to tell over my exhaust.

You don't have to have a piggyback to put in a boost gauge. One could install one to see what their stock boost is. Plain and simmple: Boost gauges are fun-tuned or stock.

Thanks man.
I appreciate it. It looks like mine is fine by the vacuum being the same with you guys. I'll drive around a bit more to see if there is any fluctuation with the boost. There's also a possibility that the gauge isn't as accurate.

I'll take a pic tonight. I have a slight problem though. I just went driving and it was the first time driving in the day time with this gauge. It was very hard to see with all of the light coming in. I either have to go with a clear lense or get a different coverthat helps cover the gauge from the external light.
