Adam,

I got that MBC that u suggested to me.. I cant get over 10 PSI out of the Autometer Gauge i have..  I have turned it and made several runs to test it and no change.. how much do you have to turn it for it to change the PSI? i have turned it about 2 turns and no change.. am i doing something wrong?
Robert,
Make sure the ball and spring are seated properly. With the lock nut tight there should only be a few threads showing on the bolt at 14psi. The oil coming out of the breather is blow by or like others mentioned it could be a clogged pcv system. It is normal for a fresh engine to have blow by for up to 3k miles.. If your MBC ball and spring are seated correctly check your actuator and make sure it's functioning properly... On my TGP I have my vent connected to a fitting on my k/n filter which helps remove crankcase pressures, that will keep the rings from floating and consuming oil...

Excellent!! Thanks again Adam!! I will investigate the MBC to make sure it's seating properly. Also I'm going to see what I can do about plumming a vent to the filter. Thanks again Adam!

Excessive Blow By or since you just rebuilt it (right?) it is still seating the rings. 

You could put a catch can then a filter to help aid in the oil spewage.

Yes it is a fresh motor. That makes plety of sense now. The rings r still setting and it is building pressure in the engine. I'll have to male up a trap that will let air out but keep majority of the oil in. Thanks

Ok.. Well got the TGP back running again.. :icon_cool: I had ordered another Boost Gauge b/c i thought that my old Gauge readings were off.. So i got my new gauges and a triple gauge pod for my air/fuel, and boost and maybe a volt? but anyway i hooked up the gauge as you can see where i tee'd it in below in the pictures.. After a big setback of the tie rod end coming off while driving and changing one end and one inner i drove the car again and snapped a pic of the gauge trying to show it how it does not go past 10...  The chip is tuned to i believe 14 PSI MAX? and i have a MBC.. The dang screw is nearly screwed all the way in and still cant get boost over 10 PSI..  Besides this problem i cant figure this one out either.. I replaced the front struts and the ball joints, wheel bearings, tie rod ends, brakes, and CV's i rebuilt so its all new.. When i take off and it boosts the front end gets real tall all the sag comes out but theres barely any and the steering wheel gets loose..  Its like blown struts but i just replaced them.. Also if i just push down on the front end its not stiff like most.. It has a few bounces before stopping.. COuld i have worn springs or something? IF i push the front end down by hand like 3 times it will bounce 3 times and then stop like it just got stiff..

Im thinking here while typing.. Maybe b/c i have 94-96 GP 5 spokes 16x7 and have 245/50/16 mounted on them.. They are puckered b/c the rim isnt wide enough that maybe the tire is growing?? I can try running the stocks but really dont want to b/c they are so dry rotted the tread is coming off..



EDIT*** Also i forgot to add up above that i cranked the the BOV tight thinking it was leaking under boost but no change..

WOT Snap shot of Gauge.. Will not go past 10! GRRR


Where i have the boost Gauge Tee'd in

There's no EGR anymore so I don't need a vacuum supply for that so that's blocked off. Also no more purge for emissions so mo supply for vacuum for that either. That's y 2 port are blocked and 2 are being used.  1 for the FPR  and MAP and the other for my boost gauge, HVAC, cruise and vacuum ball.

Slight vacuum leak anyone lol. Just kidding. Well if u figure out why your MBC only goes to 10 no matter how much you crank on it, let me know cause I have tried 3 MBC and they al do that for my car aswell.

You have them blocked of at the trottle body too?

Maybe the wastegate actuator  is regulated to 8 psi for the stock tune or some crap. Once it hits 10 psi it opens and drops the boost level to 7-8 psi. Cuz that's what seems to happen to me.  Could the wastegate actuator have anything to do with it?

The wastegate actuator is set @ 4lbs from the factory. Most likely that is your problem, the diaphragm has busted and it can't regulate boost. Since you have a MBC the computer has no control over boost. If it senses knock it will pull timing but that's it.
