I received my invida down-pipe with cat delete (+ already stage 1 withe Q-300) today and installed it and uploaded the cob stage 2 91 oct LWG map and i was pushing 29 psi , then i changed back to stage 1 91oct LWG and still same problem.
I had to take my intake off the car to get to the bolt on the down pipe, and it ended up being a whole turbo housing removal, maybe a loose vacum hose?
Also in not throwing any code from my 02's sensors. Also boost pill is still not removed.

 

Are you hearing any unusual noises?

 

remove the boost pill. do a datalog with the lwg map and without post them up here

 

no unusual noise i can hear ill have to listen to it again and ill get a post up for a mapping once i get home

 

I thought you have to remove the boost pill to run the stage 2?

 

you do, so it's odd that its hitting 29 psi. Is that a gauge reading?

 

maybe WGA??

 

i went through the whole car again and found that a vacum hose had a crack in it (probably from me) and i replaced it and falshed the car on stage 2 91 oct lwg and it fixed it(24 psi +/- .9, well thanks for the help anywats
