I have been trying different adjustments on the valve and it doesn't seem to change much if at all. Driving around flat streets and such is no problem at all. It's when I start to make the mountain climb it just doesn't seem to like it AT ALL. Bucking bronco. Still messing with it may give up soon and put the mr valve back on. Thanks for the help

 

I'm going to go to an MR valve, too. I don't doubt that some can get this valve to work as desired, but there must also be conditions where this valve just doesn't work out.

I had this problem too with my Forge RS BOV.

Simple fix: Bought an FP Green

 

So you're saying your Forge RS no longer flutters because of the FP Green? Must be nice.

 

If anyone wants.. I will trade my APS Dual vent Valve for and Forge RS Valve pm me

 

I emailed Forge last night, and they're buying it back. Now that's a stand up company.

 

idk bro i rather use hks recirculating

 

Now that sounds like a great idea.

I dumped mine for a free hks clone I had to evaluate today. And even VTA until I get a recirc kit the car drives 200x better. That's just plain sad.

A knock off... vta... > rs
sad.


Anyone wants this thing feel free.

 

how weird... I clearly remember better throttle response after installing my RS valve & it holds boost just fine. Overall quality is top notch, I considered it an upgrade from my MR valve from a performance oriented perspective.

For 'driveability' I recommend keeping your EVO completely stock, or even better yet, go buy an accord.

I'll get right on that.

 

says the guy sponsored by Forge. Go figure.

 

I can make it flutter by how I modulate the throttle. It doesn't flutter in 5th gear under a stead 5psi like it did with the stock turbo. I can pull hills on the highway with very little to no flutter. I believe the larger wheel helps against it. I never had a problem with the Forge when I still was using the stock intake.

 

unable to ever get the adjustment right. I have gone back to the MR valve and it is for me night and day better. No more frustration. Thanks for the imput.

 

For those that actually got it to work for you what settings are you keeping it at on high boost. The knob has a positive and a negative setting. Which way is best and what do they mean? Positive hard or soft or Negative hard or soft? Help please the flutters are driving me crazy and I've only had it for one day also if I change back to my stocker will that mess with my tune?
