Boost gauge issue

[DropSomeMoney]

Ok I hooked up my boost gauge correctly show in the picture. The gauge shows ~25 when at idle. But when I accelerate it jumps to 0 psi and nothing more. I did a vacuum test on my lines and the read at 18. What is my problem? Could it be a bad gauge?

Do you have a MBC? I cant tell if the "T" is hooked into the line thats hooked into the intake either. Is it?

 

[DropSomeMoney]

No I do not. It seems one was setup before and was taken off before I bout this vehicle though.

Yes it is.

Here's a full picture.

Ok. I have learned the hard way. I bought this gauge off of eBay. What a pos! I took it out and hooked it up directly to the T and it was off. I only spent $20 on the gauge but I do not like throwing money away at all. No more eBay junk for me. Every time I tapped on it it went to a different setting (Lmfao). I'm just glad I didn't buy anything important off of there.

Drive it safe until you can get a new gauge, boost is not one that can be wrong. If it is not accurate you could lean it out and cause damage to the engine just my .02

Buy a gauge from a know company. Aem/autometer

Thanks guys! I've been looking into them more. So I've replaced the vacuum hose I cut and going to buy a quality one.

Ok guys. Thanks for your help before. So I bought a new accurate gauge and everything works great. I'm boosting at 15lbs max. My next question is. Should I be boosting this high with no upgrades?

I would get some supporting mods first. I would stay at 10 psi. Get a manual boost controller.
