heres the deal fellas. I have a gillis valve coming in the mail as I write. my problem is, I know I am getting all 12 or so lbs. of boost from the factory but my guage reads between 5 and the most 10 since I bought it. it read 5, then 10, then I put the cold air kit on and it read 6. performance as far as boost is concerned is right on. I've compared with my buddy's tc. so how do I go about getting the guage to work properly with the gillis valve so I don't blow up the motor with too much boost? currently I just have the god damned guage plugged from the vaccum tree. any help would be awesome.

Install a good gauge. The stock units are shit.I wouldn't advise increase the boost without a good gauge. Some read high and some read low.

If the stock boost gauge is not working now, the Gillis valve won't help it. Get an aftermarket vacuum/boost gauge, preferably one that goes to 30 psi. Feed it off the vacuum tree.

Yea, I ordered my Gillis a couple days ago. I'm getting all 15 psi boost now, and I just added a K&N 6" filter mounted in front of the radiator (just behind the thunderbird emblem in the front) with a 3" flexible vaccum cleaner type hose. Before I install the gillis valve I wanted to get a better boost gauge, but I don't know where I want to mount it yet. I wanted to mount it where my equalizer is, but I'm not moving that now, and I don't think that's the best place for a boost gauge. I guess I could find somewhere for it. What's the best boost gauge to get you think?

I like the Autometer 2164 that I installed.
I don't know that it's the best but it seems to be accurate when I have cross checked against other gauges.
