I just had broken solenoids replaced, all vac lines have been replaced and i just put my new restrictor pills in. I still have boost problems. I have a 10-x-5 pattern. It just kind of leaks down from the transition. Also i spike a little bit on primary. It will go up to 11 or 12 lbs sometimes and then down to 9 or 10. Is this something I should worry about, or will the extra 1 or 2 lbs not hurt very much? My car is all stock, aside from clutch, flywheel and silicon hoses.

 

x? now the x has to goto a certain psi, what is it? it cant just be x.

here's a good site to help troubleshoot your boost problems

it's about 7 or 8... at 4.5RPMs it just says F-U!!!! and starts leaking down to 5psi

 

so your secondary isn't kicking on, start diagnosing using that link

 

I actually had the same exact problem. So I just did a silicone hose job and now the sequential system is working like normal.

 

Check to see if your charge releif valve is operating correctly. You can switch the BOV and the CRV for a little bit to check it out.

 

Try these two procedures. I just went through them and had little trouble doing the tests in a few hours total.

You can use your boost gauge or do what I did and get a big pressure/vacuum gauge from Autozone and 8' of the 1/8" rubber vacuum hose plus a plastic Tee fitting. With a long needle-nose pliers, I was easily able to drive around, do a boost test, pull off at an exit, leave the car running, and move the tee to the next location. Once you find which hose isn't supplying the proper pressure at proper time, you can go back and find the source of the problem (electrical solenoid control, solenoid function, etc)
