DO NOT BUY THIS!!! READ MY POST AND THEN CHECK FOR YOURSELF!! I bought one around a month ago and have been running it on my car until today. I fell for the easy install, cheap price, and cool factor myself. Sounds pretty cool, but not worth it. We're suppose to be running 14:1 air/fuel ratio stock. Well your engine, equipped with a re-circulation valve has already accounted for the cold air that should be re-circulated when you shift. Get in your car and turn your dash to the A/F ratio gauge and try for yourself!!! Rev your car to 3000-4000 rpm then let off the throttle. When you by-pass this, by blowing it out your "custom blow off valve" your engine runs rich. The computer tries to fix the rich mixture by adding air. Your A/F ratio gauge will MAX out at 20:1, then a second later when waaayyy to much air is in your chamber it overcompensates by dumping in fuel. Your A/F ratio gauge will bottom out at 8:1. It will eventually settle down when returning to idle back at 14:1. Not to mention I was getting 22mpg around town, then 17mpg after this install. It's not worth it. The only good way to get the "turbo sound" is to install a legit blow off valve with the wire harness that will tell your computer that you are dumping the air that it would normally still be accounting for. Nothing against BOOMBA, but this isn't a quality mod for a brand new vehicle. But if you still want to buy one message me, I'll sell you mine. ;)
I think that this comment which was posted a while ago is related to my questions below.

I am interested in buying the BOV adapter for my 2017 European Mustang Ecoboost, and I would like to ask you the following:

1. Is the BOV adapter compatible with European models? I guess EU-spec cars are MAF controlled, so according to one of your replies on a video on YouTube, as well as your reply to yuriorlov (the person who wrote the above comment), I should not use it. I am really interested in this BOV adapter but I do not want to have any issues with my engine in the long term.

2. However, in case I can use it on my European Ecoboost, do I need to ask my tuner to update the tune after I install it?

3. Will this have any negative effect on engine performance and reliability?

I think that this comment which was posted a while ago is related to my questions below.

I am interested in buying the BOV adapter for my 2017 European Mustang Ecoboost, and I would like to ask you the following:

1. Is the BOV adapter compatible with European models? I don't know if EU-spec cars are MAP or MAF or if that matters in any way in regards to installing this BOV adapter.

All of the USDM spec Mustang Ecoboost use MAP tuning for the ECU where the vehicle doesn't care if you vent to atmosphere or not. The use of our BOV on a non-USDM vehicle could potentially cause the check engine light to go on from what we've experienced. There are a few customers in Europe with special tuning that are running these without an issue, but we like to let you know it won't work without special tuning. Without a proper tune, this light would most likely remain on. Your experience may vary.

2. Do I need to ask my tuner to update the tune after I install it?

From what we've experienced on US cars, there is no need to tune these vehicles once this part has been installed. However if your car is non-US spec, we'd recommend checking with your tuner to see what they recommend in regards to running this piece on your car.

3. Will this have any negative effect on engine performance and reliability?

Since this piece is only a spacer with no moving parts and the car still utilizes its factory BPV, there is nothing to fail. The vehicle still operates in the way that it did stock and still reads the electronic signal being sent to and from the BPV. The only difference is the vehicle is now venting to atmosphere rather than intake.

@Boomba Racing as I replied on another forum, I confirmed that actually European Mustang EcoBoosts have 2 MAP sensors. One is located on the intake manifold (IM) and the other is located on the intercooler near the outlet. Therefore EU cars are MAP tuned NOT MAF. This means that European Mustangs can Vent to Atmosphere (VTA) without the ECU thinking that the air released to the atmosphere is still in the intake system and therefore injecting fuel accordingly, something that would lead to the engine running rich for a while. I had to do some research, ask a few people (including my tuner), but I finally found this very important information. It seems that someone a while ago falsely spread the rumor that EU Mustangs are MAF. Therefore owners of EU Mustangs can also enjoy your product ;)

Based on the above information, as you probably know I already ordered the adapter - it should work with no issues on the European Mustang EcoBoost. Looking forward to receiving it!

Definitely let us know what you think once you've got it on!

Howdy. I just purchased the adapter for my 2015 EB mustang. Ive had the car for a week. I love it! I installed the adapter and as soon as I did, the CEL came on and stays on. I don’t have a tune. Just a Roush CAI.

Any idea why im getting a CEL?

recommendations if you don't have a Cobb. Auto tuner... at least pick up a scan tool odb2 reader.. they're pretty inexpensive you can even download the app on your phone and pay for the cable .you can use it for multiple Vehicles whenever you have a check engine light definitely a good tool to have

Im going to get a cobb tuner soon. Probably run to auto zone to see if i can get the code ran.

It's a random misfire code usually happens when your running too lean meaning that you're probably getting too much air in... just because you have 3 codes don't freak out at first sometimes all it takes is just one to trigger multiple ones.. retrace your steps take the adapter back off before you have the codes clear and double check all your other hoses to your air intake.
