I dunno if Im imagining things or not, but it seems since like last week as I let off the throttle even a little the car jerks a little too much
I checked the motor mounts and as far as I can see dont see anything weird. Didnt hit anything.
I did swap out the springs in my BOV cuz it was giving some problems, but it doesnt feel like that kinda buck to be honest.

Any ideas for things to look for? Or am I just imagining things?

 

what kind of BOV do you have?

sounds like your bov might need some adjustment
i have a greddy type-s and it jerks sometimes when i let off the throttle after being under boost

 

I have the Forge RS
I been working on dialing this thing in, but it seems to do this now all the sudden even off boost a little. I thought the BOV at first too, but seems to have a different characterstic. Almost like a broken motor mount or something.

 

most likely the bov check the spring pressure

 

I have the same problem, I thought it was the BOV but wasnt really sure. It doesnt happen all the time but when Im not excepting it, I just learned to live with it.

How would you go about adjusting the BOV? I have the hks ssqv, I know its a horrible bov but until I could afford another one thats all I have.

 

+1 on the forge. That is what I have, and I get the same thing, here and there. I thought it might be the grease in the valve. The forge's have some kind of spring grease... I am not sure what to use, for if it requires grease, and there isn't any, you might have a sticky valve.

ANy one know what grease to use?

 

I'm guessing its your BOV. IMO, get a stock IX valve instead.

 

BOV or MAF... you could always switch to speed density

 

It sounds like your Forge RS. I have that same problem and I put my stock BOV. For some reason some of us have problems with it. I know people that never have any problems. GL

 

i have a forge rs and its adjusted all the way stiff.. maybe u can make it less stiff, but you will sacrafice performance.

 

Ive actually been working with Forge for a few weeks now on my other issues. Maybe this was related because when I put the new one back in with the bigger ports and less tense spring this started.

I talked to them yesterday and they suggested I flip the valve around for the side port to intake stream and bottom port to MAF. That helped my part throttle surging problems SIGNIFICANTLY!! Feels like it took the bucking down quite a bit too. Havent really got on it too much since doing this last night, but feels much better.
Hopefully this fixes my miriad of problems with this valve. I gotta give them a thumbs up though. Thye offered my money back, but I wanted to try and keep the valve and get it working and they offered much assistance.
