Just a quick question on the Forge BPV.

Says the green spring is pre-installed but comes with a yellow spring to be used with higher boost applications. What exactly would you consider higher boost? GMS1 or like a 20 psi tune? or is the yellow more for you guys running like 25+ ???

If anyone has it I wouldn't mind your opinion on it either

Thanks!

 

I was tuned at 24psi and was running the yellow spring, but experienced a CEL and some flutter and went back to the green spring and all was good. Then I sold the Forge and got a BOV. lol IMO just use the green spring, some guys use the yellow...just see wht your car likes.

 

No offense but if you used search you'd see there's about 100 of these threads.

I use green with 20+ tune and no issues.

 

25 lb tune. Green spring.

 

24 lb tune, green spring. I tried yellow but got a CEL for p2261 and horrible flutter. back to green and it works better

 

Same exact problem I had.

 

Thanks guys.


And I did use search like I always do, it came up with nothing but for sale adds and reviews, none of which answered my question. Unfortunately the nice thing about the site having so much knowledge is the search bar does t work as well... No offense but I'm not going to search through hundreds of posts when there is plenty of nice people with knowledge for a quick answer.

 

don't use the search here. it sucks. use google

I use the yellow on GMS1 and it has worked well, seems to hold boost better.

 

Stick with the green spring. In my own experiences with my car and quite a few other lnf's I have worked on there is nothing but headaches with flutter in particular when using the yellow spring.

 

i use green no problems,
