I've got the new forge, and it looks as though nothing can be done about the fluttering/stumbling at partial release of throttle. This unit will not be staying in my car. So I need to replace it with something that has been tested and proved reliable. What's out there that fits my requirements?

 

If you don't want the fluttering, just reverse it. I've heard it backwards and it just has a woosh to it.

 

Myself and 2 other friends of mine have the Greddy Type-S, and none of us have problems with it... Sounds great too... Although, another friend has the Forge and his is having the same problem with the fluttering... Even with a lighter spring...

 

Why is fluttering a problem?

 

The car jerks back and forth because of the fluttering, not because of the noise, but what ever is making the noise. It is a very bad thing. I wouldn't care if it was just the noise, but when ever you hear the noise, the stumbling occurs, and that is bad.

 

I have the fluttering sound when I lift off, but my car never jerks.

 

I did a search. and there are others that have the same problem as I with this valve, I guess you're lucky. What intake ru running?

 

My Buschur intake will be here monday...As soon as I get paid next month I'm buying a Buschur IC pipe with a 1G Bov. Although if you have welding skills just call adam at Z1 and buy the bov w/ the flange. (You do have to weld the flange on) Its under 50 bucks and its better than the forge for 180...

 

Buschur. What do you have?
