For your boost leaks check all charge pipes if they are stock mine had a tiny crack/slice in mine replaced it and all my boost leaks were gone! Best of luck to you!
For the stock screws hit up your local ford dirt cheap, when installing my coilovers I broke the steering knuckle bolt off they had a bunch in stock for 2$ lol
Just installed mine last night. Have it adjusted 2 turns from the bottom. I think throttle response feels sharper, & it holds boost better, but I need to tweak it a bit to find where I like it. Was disappointed that it isn't making much of a sound difference but I just realised you've routed it to a true vacuum source. Would this be what gives the biggest sound difference?
@@Nickjoenap where did it recommend to stay on the solenoid? Want more Boise but also don't want to damage anything. It still recirrculates the air like the factory one so I figured it can't be that much different.
@@damoissasicko if you want more noise make sure you have an intake and filter. this one isn’t great for noise because it recirculates so you may want one that vents to atmosphere
@@Nickjoenap I have a K&N filter & factory intake. A cold air intake may be a future mod. I think I'll trial the true vacuum source. I'll lyk how I go if you want. Thnx for the quick replies :) keep up the vids
there is no adjustment spring for vw only for ford😢 so u dont really get any flutter on other cars where u cant adjust the spring kinda sucks because i wantbit just for that sound and i dont want that pshhh sound vta gives
@@speed3.spence417 don’t tighten it all the way. i think i said what i did in the video. just have to find the sweet spot where it’s doesn’t flutter when under load but it still does a little and it won’t hurt the engine
yeah it recirculates air but it’s also set to be stiffer so that the air isn’t released it just stays in the system and hits the blades of the turbo which makes the flutter noise. the noise exits through the intake so an aftermarket intake makes it louder
@@Nickjoenap sweet thanks! I pick up my 2013 ford focus ST on Monday I wanna start with a cold air intake, catless downpipe and this blow off valve, it’s bone stock except a 3 inch cat back exhaust, any reconditions on what mods to install?
I got a DVX on my 2016 ST, haven't changed the screw adjustment. Do you need a tune to be able to change the screw adjustment so I get more flutter? Will it do any damage to the car? Ta.
From what I’ve read on forums BOVs do more harm than good and could cause problems on the stock tune BUT I would like more turbo “noise” I guess you can say. Would this be a good alternative for a stock focus st?
Yea this is perfect for a stock ST. BOVs are super popular and definitely don’t do any harm. On a stock ST they make it stronger and hood boost better so it’ll be an upgrade
Did this mod one week back. Re routed the line to my symposer delete as well. Immediately felt better response on boost. Screwed in the DV will hold boost between your shifts and that turbo lag “leash” is shortened. Snappy throttle. Screwed out gives a smoother throttle and some better low rpm intake flutter and purge noise. Not obnoxious or over the top. Love it 🥰
I have the go fast bits on my st , make sure you don't adjust it to make to much flutter or you will loose alot of power. Best thing to do is clean your diverter valve or blow off valve every 2 months. Or do it every oil change. These cars tend to oil the stock turbo way to much.
Have you ever had a problem with the stiff spring they give you? Mine tends to open alot while on the interstate at light throttle goin a steady speed. Drives the same with the factory vacuum or true vacuum
@@dylanrobinson3004 i have had this problem also even on a tight setting. It seems to do fine the best thing is to run a true vacuum for boost to the blow off valve . There is alot of videos showing how to do it.
Hey man just bought a 2013 ford focus. I live all the mods you've done mine came with alot of them already done. Just curious about the check engine light does it usually come on when the access port isn't on?
Do you have aftermarket intercooler at the time of installing gfb dv+? Because I heard that with aftermarket intercooler you will have louder turbo flutter. So just want to make sure is your car having aftermarket intercooler during the installation? This quite loud 😁
sry for my bad english - BUT: it actually is bad for your turbo! Why do you think OEMs install BOV? This "time increase" between shifting is because the compressed air ist still in the system. The compressed air is "discharging", while no boost is required, on the compressor wheel of the Turbo, because the BOV didnt fully open/open enough...This WILL damage your turbo and decreases lifetime...
@@kushtrim2915 You're wrong. Compressor surge is only detrimental to your turbo when you have surge UNDER LOAD. If you surge with open throttle, you will damage your turbo. If you surge with closed throttle, your turbo is no longer compressing air, and it just chops up the air surging back out the intake. OEM on this car is full diverter, no BOV at all.
I've installed one of these yesterday. In the instructions it says to tighten the installation screw and then half turn back. You do this all by hand. You don't want to over tighten.
Allowing it to flutter like that will destroy the compressor bearing on the turbo over time I wouldn't recommend doing this unless you don't care. Get the turbosmart plump back recirculating bov. It works just like the factory one recycling to the intake without the noise and is better quality and won't hurt the turbo over time like this will.
compressor surge doesn’t really harm the turbo unless it’s under load. i’ve had this for a long time and had no issues. this is adjusted to be stiff enough to not let it flutter under load and only happens in low rpm
Not true. If you have turbo flutter while your making boost and ok the throttle then that is bad. Turbo flutter after you let off the gas and release boost pressure is just fine. Not going to cause any problems.

thanks i will try that!
Just got this instead of a turbosmart. I'm excited! Gonna install soon
i was about to get a turbo smart. does it sound good?
@@ryanweinstock7977 turbo smart sounds pretty good, i have one on my ST but planning to get a GFB
For the stock screws hit up your local ford dirt cheap, when installing my coilovers I broke the steering knuckle bolt off they had a bunch in stock for 2$ lol
if you turn the diverter valve more, will it create more flutter ? :D Finally found this, can't believe I have lol.
Just a quick tip. You may want to apply a little bit of grease to the spring if you plan on the GFB dv+ on Long term
Any type of grease in particular ?

Mine isn’t routed to true vacuum I actually switched it back to solenoid controlled when I installed it

Hey brother I have 2 questions, did the blowoff valve give you the CEL? and does the intake help the flutter? I have a k&n one
his CEL is from his downpipe i think.
Sounds perfecto, any louder would get annoying and over the top. Just my onion 🧅 it may stink

Does the turbo flutter noise happen because of the blow off valve? Or how does that work?

Does any of you guys gfb dv+ Open up at light throttle on the interstate? Mine does it alot with the stiff spring it comes with
Crist Road
Will I need a tune if I put one in?
No

no there’s no tune needed. just don’t tighten it all the way or all the way loose and you shouldn’t have issues
I don’t have the metal plate, do I need it?
Buck Burgs
May i know how many turns are your setup of DV+?
Did you do 2 quarter turns to loosen it? Or 2 full turns to loosen it
Could this work on a fiesta st as well?
Was the vacuum leak caused by the true vacuum source? I’m planning on doing mine soon
no i don’t think it even had a vacuum leak now
Mine sound the exact same!
sounds good. nice ST
I don’t have the install tool🤌

These aren't blow off valves, they're diverter valves. And neither do any harm.
190k mi with the BOV I installed. 2013 focus ST 3 factory everything still minus the water pump blew out on me lol.
Just throw ots tune on
Hahahah this guy.
My boomba gets really dirty and gums up. Gonna replace mine I think.
Yeah since it’s open mine had lots of gunk in it too. Pretty sure the go fast bits one actually did make a difference when shifting and felt better

It's not making any sound for me
might need a louder intake
That's a good thing, these valves are not supposed to make more noise.
Should just run a true vacc would’ve been cheaper
i used to have true vac on my boomba bov but this is better
Do you have aftermarket intercooler at the time of installing gfb dv+? Because I heard that with aftermarket intercooler you will have louder turbo flutter.
So just want to make sure is your car having aftermarket intercooler during the installation?
This quite loud 😁
yeah i have a depo racing intercooler
It's essentially the same volume/loudness, but with a bigger intercooler my flutters became slower and deeper sounding

Compressor surge isn't actually bad for your turbo, it just increases the amount of time until you can get onto boost after shifting through gear...
