AP bov...rpms weird
Hey guys i got the evo running and i changed a few thing on her in the goal of 410 on the stock turbo. Which reminds me i need to change my sig lol. Okay so i installed a AP bov and have it running 50/50. the bov is adjustable and this is my first time owning an adjustable bov switching from the MR bov.
Okay with that said when i first took the car out for a test drive i had the boost turnd down to 13psi...the bov was working great.....so i started to turn up the boost and the bov seemed a lil soft fluttering a lot at low rpm so i tightined the spring and turnd the boost up more and it started fluttering again after 6 4th gear pulls with the car im at 26psi and now my rpms raise 1500 1800 when i let off the gas to shift.....
please help me out guys as like i said im really new to the adjustable bov. and im still getting low boost flutter.
thanks a bunch guys!

First of all, is it APS BOV or AP? please make sure what you typed, it's confusing. I only heard APS bov
Secondly, the JDM MR/IX dv does flutter under low boost/partial too, I drove 3 different evo IX and they all flutters under light throttle, in fact I just drove one yesterday, it's not like what people said it won't flutters.
I am currently running APS BOV in my evo 8 too, this is by far the best bov ever, it nevers flutters under any amount of thorottle. I bought it brand new and it works better than the JDM MR DV I had, it even holds more boost.
but now I have to say APS BOV is not for everyone.
Your problem reminds me of "throttle hang" which means once you let off the gas the rpm raises. My buddy had the same problem when running the APS bov in his IXj, and I even put my APS bov in his evo ix and the throttle hang still occurs, in the end we sold his APS unit b/c it just doesn't work for his car.
