Lol... hindsight 20/20. I hope that fixes your issue. Make sure to double check Orings, etc.

So fixed the boost pipe and still same issue. My thing is why would it hold boost just fine before 5k rpm and than start going down. Wouldnt it not hold constant boost the entire time and just above 5k rpm.

Fuck me I feel like selling the car now. LOL ugh

Could it be an issue with the tmap sensor? I ordered the one below.

Im no expert but im pretty sure that the Stock turbo just looses steam after 5k rpms.

How many miles on your car?

Have you tried to load a OTS map and log to see if the issue persists past 5k rpms?

53k miles.

I am going to try and OTS map to see if I am getting the same issue. If not then its the tune.

How did you determine there was a leak in that electrical plug? Where does that plug go and what does it do?

I have no idea what it does. But I was doing boost pressure test and heard leak from it.

Truly hope you find the leak and put your worries to rest once and for all!

Broke this hose that goes into the charge pipe. Looking for part number.

Yeah, it looks like your boost is actually tracking target now, even if it remains about 2psi below. Definitely not the huge drop off up top that we saw before. It kindof just looks like you arent going to make more than 18psi. Turbo (WGDC) looks nearly maxed out at the top of the pulls. I didn't really look at timing, but based on the boost i would expect these to feel tangibly different than the old ones.

Logs look clean as can be.

Here are some of my latest logs. I'm FBO with stock turbo and stock fueling. Cary Jordan custom tune w/93 octane:

Logs performed on 1/16. Third log done after some adjustments by Cary... I'm at a crossroads. I have 68K on the clock and contemplating either going PS2 and XDI or just get into something new.

Same here. Mine is at 57k miles. I am not sure how much more money I want to dump into it.

I may just sell and do employee lease program at work. I get to keep the car for a year, no insurance, no taxes and no maintenance. Right now we have the 330, z4, x1, x2, x3, x6, 530, 540, 550, 430 and 440 on the program. The x6 and 550 are the most expensive at $550 per month.

Still off target but not by much so i'd say its good enough.

I ordered bigger o rings. I will be swapping them out when I get them. Hopefully with them I will get closer to target.

Hmm... What specifically in the third log is no bueno?

Is it the HPFP calling for 2100 psi and actual at 1500ish?

Thats what i see in the 3rd log. Also, you really overshoot boost target quite a bit at the beginning of the pull then continue dropping below target more and more throughout the rest of the pull. WGDC isnt crazy high but that's quite a bit of boost drop off.
