Brake booster check-valve bad?

[KKell83]

Hi all,

I'm still in the process of tuning my Procharger setup with PBD and came across something weird after doing a WOT pull. I have codes P2005 and P2006 (2018+ manifold - using IMRC's). Well the car doesn't like to rev and sounds weird. I parked it over night and noticed this morning that most of my lines going to the aspirator are kinked/sunctioned... I removed the hose from the brake booster line and everthing BREATHED, and the kinked/sunctioned lines went back to their normal state.

I try to blow through the brake booster line and nada (how it's supposed to be), but when I suck I'm also getting nothing... is it bad or an I just not opening the value enough?

---

update - pulled the brake booster valve and played with it until it became free. Noticed also that I did 'flip' my aspirator but the lines were attached according, but it probably wasn't good enough. I cannot see why it would make a difference but I'll reinstall it and try again.

Update - I reverted the aspirator based on what most people do here and same things, P2006 came on and my brakes became extremely touchy. Pulled the aspirator line from the steal hose going to the brake booster and an breathed again, that very line would accept pressure nor vacuum until I removed it from the brake boost then it also made a sound (got air). Push though the brake booster check valve and nothing, suck and it works...

Any ideas?

Couldn't figure out my IMRC issues - there's talk that I forgot to add in a check valve (which they're right) but I was already underway adding in IMRC lockouts.

Car runs great, thanks PBD (Rob).
