CTATV Posted November 2, 2010 Share Posted November 2, 2010 So my Forge BPV for my LGT came with 3 springs, a yellow, a red, and a blue; and two shims. It came with the blue one already in the BPV. I did a little research online and this page says: http://www.maperformance.com/forge-valve-spring-tuning-kit.html Green - 5-15 PSI Yellow - 15-23 PSI Blue - 23-30 PSI Red - 30 + PSI FYI here is my tune on EFI's Mustang Dyno AKA the dream crusher lol (it scores a good deal lower than most dynos http://efilogics.com/dyno/graph.php?gb=0&hp=1&torque=1&boost=1&rpm=1&sl=1&sln=1&runid1=832&rgb1=000000255 Link to comment Share on other sites More sharing options...
GTTuner Posted November 2, 2010 Share Posted November 2, 2010 Are you running a top mount? Start off with the blue and see if you get any compressor surge. Link to comment Share on other sites More sharing options...
CTATV Posted November 2, 2010 Author Share Posted November 2, 2010 Are you running a top mount? Start off with the blue and see if you get any compressor surge. I ran the blue, no compressor surge, switched to the red, couldnt hear any surge but dont really hear it "blowing off" so to speak... If I data log or look at data on my Access port looking for this what value(s) should I be looking at:confused: by compressor surge you're talking about the sound this car makes right? Yes i'm running a Perrin TMIC. I guess I should post the mod list... let me go find it [ame=http://www.youtube.com/watch?v=RuzyaWEqo58&p=8D6B2D2E2D154F12&playnext=1&index=5]YouTube - Custom Built Subaru Legacy Spec B Turbo[/ame] Link to comment Share on other sites More sharing options...

GTTuner Posted November 2, 2010 Share Posted November 2, 2010 Compressor surge as in what I call a "horse laugh" LOL. Looking at your boost levels I'd stick with the blue. I might even try the yellow. I personally am a fan of running the weakest spring you can. A quick open of the BOV/BPV seems to help lag between gears by not killing the compressor spool. You might see some MAF fluctuation when you close the throttle under high boost, not sure. Link to comment Share on other sites More sharing options...

I'm at least going to go back down to the blue I think Link to comment Share on other sites More sharing options...
CTATV Posted November 2, 2010 Author Share Posted November 2, 2010 So just had major issues. Tried to flash to a different update of my map (reflash) and then car sputtered above 2800rpm reflashed same map again now running better but something still seems up. Went back to plastic stock Recirc valve for the data logs. Going to try and figure how to upload them now Link to comment Share on other sites More sharing options...
