The Nameless Performance FA20DIT Wave Spring Bypass Valve ensures that your charge circuit purges quickly, without restriction, and holds boost better than even the factory restrictive valve.
We have run these successfully with and without tuning, but the behavior of the valve is identical to factory, so the only need for a re-tune is if you've got the vehicle tuned with an already leaking valve and are replacing it with one that does not leak.
Each time we tell people the name of our business, we have to explain why we chose to call ourselves Nameless Performance. It's quite simple really – it exemplifies our business model and our sense of humor. As eBay and the internet provide a flood of overseas products into enthusiast hands, paired with little to no customer service, customer involvement or qualification, it became evident to us that a radical alternative was necessary. As enthusiasts of pretty much everything mechanical, we have had very few experiences with manufacturers that were as personal and connected as we would prefer. So we decided to make that company a reality. When discussing what to call this company, it was evident that using our names or some pairing of hyperbole and motorsports catch phrases was not going to convey anything about us or our customers or why we do what we do. So why not put out a name that begs a question.
