boost problem

[1g_talon]

i cannot hold boost. i try running stock boost hooking the vacuum line from the j pipe straight to the waste gate without any boost controller. people say that will be for sure at stock boost. i keep on getting boost up to 20 psi.

would a boost controller help hold boost?

Is the car modded at all?

if you have a free flowing/modded exhaust it will cause boost creep aka run more boost than you want too.

Please provide more info on teh car so we can help you better.

yeah it's modded.
16g/manifold, fmic, short route piping, hks bov, intake, 3' DP and catback, 2g mas, still on stock fuel. ecmlink too.

With that type of setup you have to already have a boost controller, give some more info about the car and what its doing

[turbotalon1g]

Well assuming its internal gate, you basically don't have enough restriction to hold boost that low.

Easiest/cheapest route would be a MBC from MAP or DB, I'm sure they have them on the shelves for cheap.

Is this the same car with the clutch issues. If so you shouldn't be doing boost pulls until you fix your tranny problems
