Is this correct?

I installed my Greddy elec boost gauge and EGT tonight. Is the gauge supposed to read vacuum most of the time? when I accelerate it goes up to zero then when I punch it it goes up to near 1.0 bar. It also idles at vacuum which I believe is normal. Does this sound right to you?

yea............

you don't like it is on boost all the time don't you?

perfectly normal readings.

ok thx for the replies. I was just making sure I did it right. OK so one more question. To install the egt probe you must have your manifold drilled to fit the piece in. Is that something I can do myself or should I take it to a machine shop? I have a tap and die kit.

depends on how comfortable you feel about it. when i first got my car, i said no way i would do it. however, after much research (and a few trips over to scoobymods.com

), i'm now very confident i could do it without problems.

my only problem now is a. finding the time to do it and b. the freezing weather here in pa.

lilsix · 01-27-2005, 12:46 AM

So is the tap and die kit all I will need to mount the probe?

2ndGearFling · 01-27-2005, 12:52 AM

yeah that should be all that you need.

dr_wheel · 01-27-2005, 12:57 AM

a drill press would be nice but not required. also drill slow and use cutting oil.

not a problem. I can't remember if scoobymods shows attachments to guests or if you have to create an account, but there should be alot of pictures in that thread to help you along. If you don't see them, you may want to create an account and login.

Heck, you may want to create an account anyway. Lots of great info over there...
