explain to me

[kiddenvy]

so i just got my fuel in and i turned the boost to a reasonable 20 psi, holy go d it pulled hard, for a while anyways!! it soon dropped down to 13-14 without me ajusting the hallman, so with a leakdown test i discovered i had a crack in the stock licp, so its now replaced, during leakdown, i can hold 13 psi, with no leaks heard, but on the road no matter where the hallman is posistioned i only spike like 12-13, what else could it be?

 

[andymoraitis]

Does it go higher if you turn up the boost controller or does it run 13 psi no matter what you do? If you're turning up the controller and boost isn't rising, I would either suspect another leak or your lines are incorrectly installed for the boost source. Also, are you tapped in for the boost source on the J-pipe/LICP or off the BOV?

Let us know,

no matter where i adjust the hallman to all i can get is 13psi, im almost positive i dont have anymore leaks. the mbc is tapped into the licp. also i never messed with the mbc, and it ran 23 the other day before this started happening

Try throwing another MBC or a bleeder T on the car to see if the Hallman is working.

Yup, that's a good idea and I'd also take a look at the wastegate arm to make sure it hasn't fallen off. Even if it's loose, the flapper will blow open under boost and it will only hold very little regardless of what the MBC's set to.

Check that as well and report back with your results.

ok, so i swaped it out with my buddys gfb mbc, and i got nothing, like 7-10 psi. sweet huh, im getting so pissed, and the wastegate arm is fine, not lose at all

You also can check to make sure the wastegate arm isn't stuck I had that problem on mine. I would only get 7 to 10 pound of boost.

how do i make sure its not stuck? can i move it on my own will?
