try flipping it 180 degrees, part going into tip looks backwards from the N75 on my car, but I use a stocker

Once you have confirmed your n75 orientation is correct, check fuse 34.

Long leg of the N75 always goes into the TIP. I can't tell what's going on from your pictures though.

long leg in to turbo inlet pipe

Have you pulled and checked fuse #34?

[germanengineering g60]

Fuse 34 was fried. What could have caused it?
But still 9psi while running on just the n75 Jvalve.

add some of those missing hose clamps too

that was just for the pic. they were all clamped down when testing.

your link just confirmed that I installed the Jvalve correctly.

Two things:
- Check and make sure you don't have a short in your N75 plug or wiring (do the same for the N249 plug as they share that fuse).

- Pull the fuse again to see if it's fried again. If it is, that will confirm a short - if not and the code is gone, reset the ECU by pulling a battery terminal and you should be good.

Put your old N75 in and see what happens...

I put a OE N75J in my car After my tune and was down to stock 15psi, put the old one back in... back to 22psi

I broke a nipple off of my stock one. the funny thing is that if I bypass the Jvalve and just go with the MBC I cet stable 19psi without spike. but people say its not safe so I spent $150 on a Jvalve and its a no go.

[Marcus_Aurelius]

Well, if you're running solid with the MBC, why bother fuching with the N75? Just set the MBC to whatever boost level you feel is appropriate to your mapping and forget it.

it jerks when letting of gas so Im thinking the N75 will take that away

[germanengineering g60]

removed the n75 and running 18 psi without the n75. but I need the n75 on. please, any help?

[toy4two2]

buy another N75, non-race, remove the MBC

[Pass18t]

The code is electrical related, not performance related. Wiring, connectors or N75 itself. Did you start/run it at all with it unplugged?

[germanengineering g60]

found a hole in my turbo inlet pipe. that was throwing it off and now is all well. stable 18 psi.
