So Im getting a pretty aggressive flutter @ lower rpm and Im starting to point my finger at the n75 to be faulty. Question is there somthing I could log to diagnose the n75 to be at fault? I was think boost leak but ive check majority of the main lines, than I was also thinknin dv but that doesn't have more than 300 miles on it since its been replaced so I slightly ruled that out. Its weird my boost gauge is stuck @ zero around the same time I notice the flutter.. any ideas? 

Uh. Boost leak?
Describe how you checked "majority of the main lines". Tried pressure testing the intake?

so, can we expect you to post logs at some point? :P

Anyway, n75 diag has been discussed to death. I don't really want to do this here, it belongs in a mechanical problem forum :P

Convince me why I should go through this exercise AGAIN (for the millionth time), and i'll post a basic n75 diag list.

Sorry Nyet I thought about posting in diagnosis section but didn't think I was technical enough to do so. I posted this when I had free time in the office. I did run a search but only on this forum as it's the only 1 that ppl makes sense, I will post the logs that I of course took while my platforms got the flu but I got to find my fkn flash drive.

When I say checked for leaks I mean I visually checked the line running from the intake/mani, n75 lines and dv but have plans 2 put it on the rack and get down and dirty if I don't figure it out during the week.

I just thought id reach out to my fellow vaggers on nef  in case  this was common.I'm on going my search now that I'm at home...

I've yet to find a leak with a visual inspection... pressure test.

N75 diag is easy; disconnect electrical connector, make sure boost is limited to wg pressure

disconnect wg line, make sure you can get boost higher than wg pressure (CAREFULLY, you may overboost).

If both work, log and make sure output wgdc results in a sane, predictable pressure somewhere between the two.

I vaild that advice 100%..I just got back inside after finding a big ass gash between the tee to the boost gauge and the pressure switch 2 my wmi using the old blow in the straw trick..got damn cloth braided vac lines lol, soo relieved that I might be able to flash my meth file back in..Im still going to run a pressure test cause im sure theres more and I'll also post up logs 2maro hoping for improvement guidance from you legend. Thanks to the both you. Especially u Nyet, even tho we lost Daz ur like 1 of the few that I look forward to read when I log in..

There's a Software to every Hardware..

It sounds like your hardware isn't spot on.  Logs aren't needed until then.

haha not at all, I dont think it will ever be spot on but I always like to know what my car is doing regardless. 

Disagree, you can always use logs to diagnose.

Logging to TUNE, however, is pointless until the HW is 100%

Of course.  But I can guarantee that 90% of people here don't do that.

But they should :P

I know I do. for exsample my guage wasnt working so I was using pvdkds to really see what was going on, I thought my n75 was at fault so I posted up and was curious if ldtvm or something can pin point it. I'm not sure if dwkrz is considered diagnostics but I keep my eye on it quite a bit as well. I'm not sure if fcmend is affective or not but I do take alook at that from time to time along with a couple other odd things

I guess I could consider myself apart of the 10% according to adam ::)

If you're ever sick of dealing w/ 710n's after whatever pressure you send thru it what would u go with??

Honestly?..

710n

Lmao ;D ;D...if only I can carry em in bulk ::)
