Boost and restrictor "pill" questions

Postby my04gt » Sat Nov 05, 2011 3:27 pm

Hi Guys
Im new to this MY04 GT liberty setup.
Of course im chasing more ponies then it came out with standard.
I have owned the car for approx 4 months now and have had to do many basic service items and repairs, the car is very very clean and has been maintained by Subaru, BUT I think the last owner was a tight ass and didnt have basic repairs done.
So far i have found the variable cam timing valves were siezed (all fixed now)
Front 02 sensor was faulty (causing poor idle) all fix now
Air flow meter was faulty (causing poor throttle response) fixed now
Cleaned out the waste gate valve (feel better now) but still not right
My problems are this!
I installed a boost gauge, as the car still feel very slow/restricted, i found the boost to be hitting a maximum of 7psi,
So i installed a Manual boost controller (just too see if it made a difference) I found 2 things
1/ there are "2" pills in the waste gate vac line ("1" on the waste gate side and 1 on the other side of the "T" piece (is this correct) i wouldnt think it needed 2 restrictors ??
2/ when i increased the boost manually to 15psi/14psi or 13psi, the car felt like it hit a limiter
I must admit as much as i love the look and feel of this baby, my xrt6 was alot easier to play with and understand (managed to get 357 RWKW with very min mods and 10psi boost)

Come on guys make me pround and help me get this girl working correctly

BUMP

Ok let me think this out (feel free to jump in)
1/ "2" restrictor pills would "increase the boost if anything" (seeing the vac line is restricted)
so why would the boost be sitting at 7psi max?
2/ possiable actuator failer (leaking) not allowing boost pressure to increase.
BUT WHY would i be able to manually increase the boost level to 13-14 psi ??? (but it does bleed off after holding thottle open) WOT

Come on guys some help would be appressiated!!!
