R33 Just Seems Slower

[engo]

ey guys, i drive an r33 s1.. my mods are 3 1/2 inch exaust (all da way) t04e garret turbo, high mount manifold, 38mm external wastegate, hks fmic, bosch 040 fuel pump, turbosmart stage 1 BOV, turbotech boost t (running 14 pound) (JUNK, puttin on a trust one very soon), blitz pod filter, exedy heavy duty clutch, and microtech lt12 E.C.U... i had the car tuned almost 5k km ago,.... lately i have noticed that the car has no where near the power that it used to... when i give it some stick.. the boost shows up to hit the 14 pound mark as per usual.. but the turbo seems not to be sounding as tight (if that makes sense.) when it used to spool it would be a tight winding sound now it is more like a loud hissing sound... the car is goin in for a full tune and fluid change this week.. but i just want to have an idea what could be happening... i am suspect for leaks but it seems fine... however i am really suspect on my BOV.. there is oil spray from it onto the wheel guard (it hidden under the driver side) and the valve is easily moved by my fingers when i have checked it.... anyone have any idea's??.. n e help would be appreciated... thanks guys!!

If your car is running a atmo BOV, get rid of it and go stock... then get a nice dyno re-tuned... this should fix all your issues.

Good luck

hissing sound could be a boost leak, check bov, and all cooler pipes + hoses for holes along with clamps

could b the turbins in the turbo grinding on the intake of the turbo..or leaks from the bov.
