boost problems

[SilverStr33k]

so i have stfa's up down, left, and yes...right, i cant find an answer, i am stg 3 on awe chip, my car had an hks evc boost controller running 20 psi, it was removed and the n75 was hooked up to control boost, not im getting 26-20 pound spikes dropping to 16-18 psi creaping back to 20 by redline, and sometimes when i floor it i only get 6 psi till i lift and reapply the throttle, any ideas?

glad everyone is jumping to help, dont worry, it doesnt matter anymore i just blew my front diff

[quickaudi]

6 psi would signify boost leak

have you checked your codes?

[Evilevo]

the car is tuned for a N75?

[SilverStr33k]

the codes are random multiple cylinder misfire, evap leak (small), o2 code(test pipe related), and yes the awe chip was tuned for the n75, however the valve was capped off and unused for the past 2 years because the boost was being controlled by the hks boost controller, and better news, not the diff, i had an inner cv joint let loose and it was transfering noise vibrations into the diff casing which made me assume diff, thanks for any ideas u guys can come up with

Sounds like you might have bad EGTs throwing your car into limp mode.
Vag-Com might not read a bad EGT yet.

well i dont have a vag com, only a code scanner, and its weird, because im only getting limp mode(6-7 lbs) sporadically, but if i lift real quick n mash it again, its spools right up, im startin to get really sick of this car...

any ideas guys??

my car is getting the limp mode with misfires on 4,5 and 6. i only got the EGT code 3 times and now it is just the misfire codes. but there is a lot of no boost or just boost up then stop and then start right back up then stop again. i am working on getting a boost gauge.

see im gettin misfire codes but no egt codes

wanna boost leak test your car?

i have a tester. do you have a regulated compressor?

[haus4]

are the misfires only on one bank? Do you have a CEL? You really need to pressure test. I could be simple. But if u have multiple misfires, even when idling I would say its time to use the search button.

I would check to see if all your your injectors are properly in... one of mine was out, and i could only get up to 5 psi and it sounded like i was running on 4-5 cylinders.

i do have a compressor, possibly this coming weekend? it should be coming back from rennart by thursday(new axle)

[SilverStr33k]

and, I checked injectors and stuff like that, im thinkin coil packs or idk...im gonna wait till i can put some miles on it cuz i just got new plugs(bosch sidefire) and i want to see if this helps it at all before i throw more money at it, im gonna try and have rennart vag-com it while its there gettin the new axle.
