I am having issues with boost in my car. I just recently replaced a blown turbo on my car and I was only hitting around 3-4#'s of boost. Fixed a few vacuum leaks such as replaced the grommets on my injectors (ones on there not even fit for my car!) and we adjusted my bov harder since it was set on about the softest setting possible.....but im still only hitting about 6lbs.....the only possible thing i can think of is that I am missing 2 upper nuts on my exhaust manifold. Could this be my problem with boosting???

By the way, i have sprayed EVERYWHERE with starter fluid

put the nuts on your manifold too

I know for a fact its a boost leak. You car really hear that sucker when you get on it, and if we disconnect the w/g line the sucker makes 17psi hehe.

no if it makes 17psi with the wg unplugged then you need a boost controller

With the w/g not opening(disconnected) ofcourse its gonna make insane psi. We just did it to see if it would make MORE than 6psi...

He wants to run it with whatever the stock w/g will run...

When i said hitting 6psi that was in the higher gears on the highway...i'm only hitting around 2-3 in the lower gears right now

If what you are saying is you are missing 2 of the 4 manifold to motor nuts, then yes that is your problem. An exhaust leak before the turbo will cause sluggish and lower boost. If you are tuning it that way it will also effect wb readings.

Its going to be fixed soon. We cannot hear an exhaust leak though, but thats only at idle, not while driving....

you have an exhaust leak. Fix that then if that doesnt fix the problem fix whatever else you find. Actually fix everything then I guarantee the problem will go away.

Make sure all the bolts on the intake housing are in place. Like the ones that hold the WG bracket, and the housing together. Those bolt holes go right through and are a potential leak if there missing.
