Could this be a bad MAF sensor?Actual boost is dropping off when it shouldn't be. Not sure what that little spike drop is there, but that ain't right either. N75 looks "lazy" to me: don't ask me what that means (it just "looks" lazy- might be because boost doesn't look like it's real quick, hence the N75 doesn't have to react quickly?).
I can do another log. Previous owner said he cleaned the intake when he deleted the egr/asv. Should probably do a log with the n18 connected to the turbo actuator?Could this be a bad MAF sensor?
Would MAF logging with the boost & N75 help?
Maybe a look inside the EGR valve to see if it and the intake are clogged?
