G-valve only boosts 10 PSI

[anokabball24]

This is seriously driving me nuts. I took a G-valve out of my Omni, worked fine (set at 14 psi), and threw it in my Daytona. Well, the ****er won't hold boost above 10 psi. Doesn't even matter how far I have it turned in.

As far as I know, I have it set up correctly. I went back to the computer controlling boost and it hits 12-14 psi...This is driving me nuts.

My Daytona is sad because it's running rich, and is hungry for more boost.

Couple installation pics for you to look at. How's it look? I suppose I could by pass the entire W/G solenoid, but I don't think it would change anything.

well it could be the wastegate... haha what you can do is unhook the line and take it down the road (get ready to let off).... if it only goes to 10 then you know its not the G-valve... if it goes to 12 or higher let off asap and you know you CAN get there with a good set up!

im having the same problem with my daytona...i dont have my boost controller hooked up to a wg solenoid though. let me know if you come up with something. i will do the same. lol

I have mine hooked directly from brake booster to aftermarket boost controller(turbosmart) then to wastegate..... If you have the factory wastegate solenoid hooked up ..the computer will control boost.. having the grainger and wastegate soleniod running together will make you have some real problems...thats the way it appears in the pic

Well, I think I've already updated this thread, but if I haven't I will now.

I unhooked the vac lines from the WG solenoid, and now I have the G-valve running from WG can >>> G-valve >>> manifold.

I'm hitting 14 psi no prob. Problem was that the spring in the g-valve just needed to be turned way in.
