boost problem

[Talon92Black]

My car drives like it has a boost leak but i did a boost leak test and nothing is leaking. What else could it be? THX Andrew

Can you describe the problem?

Yes, describe more, but it could be fouled spark plugs , I had the same problem.

well if i give it gas the boost gauge sorta floats up and it doesn't even go faster. Its actually hard to get up to speed. Feels just like a boost leak but nothing is leaking.

It's not your clutch slipping is it? What do you hear when this happens? Do you still have the stock boost gauge? ....... Too many variables, stop being lazy and give us more detail description.

Ok well here is what i can say. i changed the spark plugs and oil and then when i went for a test drive it was acting up like i had a boost leak. I could hold like 7psi STOCK GAUGE then it would float up to like 11 and not go any faster. Then i got on it starting in first and it seemed fine. The next day it went real bad, if i give it enough gas to get it moving it just pretty much goes up to 11 psi. Like I said it feels just like a boost so I did a leak test today but nothing is leaking.

no the clucth isn't slipping

Has it always been like this?

You could have a manifold leak. Feel around the manifold for exhaust coming out of it. If it takes awhile to build boost this could be the problem. The stock boost gauge isn't accurate, though.

I wouldn't trust anything the stock boost gauge have to tell me, They are not accurate. I would go back and check the plug gaps and the wires are in correct firing order. Which plugs and gap did you install?

between the manifold and turbine housing had some bubbles coming out of it after i changed the oil and was looking at the engine
