With open waste-gate still 14 psi
Update:
with waste-gate tied open I still get 7psi @ 4k rpm, than goes to 14psi till redline...

Problem is i am running stock tune, so @ 14psi i'm seeing AFR's of 14.5 (between 3.5-4,5k rpm)
AFR at high rev's is good, 11 a 12.
My mods:
-Stock turbo
-3" Turbo back
-Pod filter
-FMIC
-EBC (turned off)
-Splitfire coil packs
-Iridium 7 plugs
-98 oct gas
Checked ignition timing (spot on -15deg)
Engine flushed
New actuator
waste-gate valve checked, all good
Any ideas???:annoyed::wack::furious:

He all,
I didn't really get any good results from the "search" so I'm trying it this way
I know that with an upgraded exhaust, boost creep could occur but i am running stock exhaust and cat...
When i floor it, boost is 0.6 bar (really steady)
than above 6K rpm the boost goes up to 0.9-1 bar
is this normal and what can i do too fix it?! doesn't seem likely that Nissan messed the turbo port up with stock setup...??
Don't know what it is supposed to do but this doesn't feel right
