Whenever I am just cruising on the Interstate and I back off the gas, I get a flutter in my BOV and my car slightly jerks back and forth. My BOV has always had the flutter but never had the jerking feeling. It is not a really bad jerking but definitely not normal. It only happens when I am in a higher gear, mid RPM's, and just cruising and let off the gas. Any ideas? It is a turboXS BOV and I have the standard bolt on mods.
Thanks in advance for the help.

 

Most strong BOV's are going to flutter at partial throttle. Purchasing a metal evo 9 BOV will cause it to be less noticable.

Did you try adjusting the spring strength any? BOVs require a lot of tweaking to get them just right for most conditions.

 

I have the IX DV on my car and I still get that "jerking" too. I think it's just compressor surge, all these cars seem to do it. Once your modded it just becomes worse...

 

haha I know what you mean. I just feather my feet when I let off throttle so make it easier on passengers. In first gear, they must all think I can't drive a manual. It's like a row boat letting off and on throttle in that gear.
