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