OK I was having some boost problems with the seq set up. 10-5-2 so after serching over and over I decided to go with the non seq set up. now I am only getting 7 psi occasionally 10 but then a drop to 7 or 8 I have switched the precontrol and wastegate plugs and plugged each of the lines in every possible combination and still get around 7 psi (currently have precontrol plugged and using wastegate lines) so my problem is not there. I still have stock dp and exhaust but have taken off the cat. I have checked all vaccum lines and got nowhere. Tonight I took off the pressure chamber and plugged those lines and still 7 psi. tomorrow I will take off the vaccum chamber and plug those lines. I have had all the intercooler pipes off several times and still get the same boost. Could my secondary turbo be bad? How would I go about checking it with the non-seq set-up? Could my BOV be bad or leaking? How would I go about checking that? Any suggestions?

 

well tonight I looked over the system again and checked for boost leaks and found none. I am getting the usual 7 psi and cant get anymore. I need some help here. I have checked everything I can think of for now and checking more each day. I have also checked the BOV and have eliminated the crv

 

What kind of fuel management are you using?
