hey guys for the past 2 weeks i’ve been trying to resolve this issue but after reading many forums and trying to diagnose i still can’t seem to find the fix.
I have a 2007 Gti that’s been loosing boost. when the car is barely at temp or after doing the first pull of the day it will boost all the way up to 14 psi for 2-3 pulls and then it will max out at 4-5psi after.
i can be driving it after a while in the night and it’ll randomly kick in to full boost for a moment.
i suspected it being a boost leak but i doubt the car would ever boost fully if it did.
i’ve also been looking into replacing the n75 considering that might be my last option.
if the wastegate was bad or turbo itself why does it sometimes boost perfectly and then not? it’s as if it’s in some kind of limp mode
i think my pcv is still working fine
i’ve replaced the dv with the newest rev
i have a cold air intake (new MAF)
3” Downpipe
pfr8s8eg ngk sparks, in the process of getting new r8 coils as i have misfire in cyl 1 and 4
i also have it on stage 1 united motor sports tune
about to do the cam follower on it too tomorrow
what other options do i have at this point?
