8-5-5 boost????? HELP!!!
 

I'm getting a 8-5-5 boost pattern... what the hell is goind on? Can someone help me with this? I replaced all the hoses and it's still a 8-5-5... Could it be that one of my BOV's are leaking? I (for some stupid reason) took the car to the dealer and the tech there replaced a hose going to my BOV... ever since then, I've been getting 8-5-5... WHAT THE HELL??? :mad:

also... could it be that my Precat is clogged? I have 104k on the engine...

could be precat or maincat...not BOV unless its installed wrong.

Check your hoses again...he didn't mess with your primary turbo did they?

You have to get 8psi for it to transition to th second turbo. if its less or looks like it may be close you may not be getting enough on your primary to switchover. Most likely you hit 5 psi at 4300-4500rpm and it just drops off there. I had a leak in my Y-pipe. Make sure its all the way down into the sleeve and the hose clamps are tight. That fixed my boost problem at switchover. Now I lose my boost at around 6krpm. I think thats due to the clogged cat. Will find out when i do the downpipe later this month.
