I don't even know where to start....
Well some of you may know that I have been having boost issues with my IX, last week I found out I had a leaking stock bov. I got another new one in the mail and installed it on friday, it ran great all day friday and was boosting normal. Today when I was driving to work I noticed I was only boosting 10-12 psi max in all gears. When I got to work I checked everything and it seemed fine, I checked if I installed the bov correctly and it was done right.

I went to go pick up lunch about 30 min ago and it was still boosting 10-12 psi tappering to about 8 psi. I'm not sure what I should do with my car, I'm starting to think my crappy autometer gauge is the problem but I'm not 100% sure. Another leak is possible but it was running perfect on friday when I installed the new bov, I was hitting 18 psi all day. I think I tryed everything with my car and don't know where to go from here. Should I just take her to the dealership and have them take a look? They aren't charging me so should I just drop my car off? If anyone has any suggestion please feel free, I'm I missing something here that you guys can point out? Thanks in advance!

 

If you are still stock(I am not sure what BOV you have) and under warranty I would just take it in.

When you hit 12psi, does it feel like 12psi or does it feel like 18psi? If it feels like 18psi felt, then it is prolly your gauge. If it feels like 12psi, do you have a boost controller installed? Also what line did you too to get the pressure for your gauge?

 

I'm 100% stock except for the K$N drop in filter, I still have the stock bov. When I hit 12 psi it does fell like 12 psi, I def lost power. A C class benz pulled on me on my way to work....
I guess I'll let the dealer check it out.-

 

That is your best bet.

 

Same thing happened to me on my VIII, I got rid of my bov and exhaust never happened again.

 

Are the two clips that secure the intake snorkel still there? If they aren't the snorkel will get sucked up into the hood and it won't boost much as it will be starving the turbo of air.

 

The snorkel is still in place. My boost has gone down even more since I posted this thread, I'm down to 8 psi max. My friend told me it's a wastegate issue because he found no leaks. I'm going to take it to the dealer and have them fix it.
