"The EFR line of turbochargers is packed full of features.

BorgWarner’s new line of high-performance turbochargers is specific to the automotive aftermarket. Traditionally, aftermarket turbochargers are “pieced” from current product lines that serve the automakers. The primary reason is cost, as it’s extremely expensive to design, test and manufacture a turbocharger from a “clean sheet.”  So, companies usually leverage current inventory to make a new turbos specifically for the aftermarket, and then call it a day. The new EFR product line has no ties to the OEM market. In fact, BorgWarner could maximize this technology and feed it into production vehicles. When engineers developed EFR, they listed features they thought would be cool, might be possible, and all the performance elements customers wanted in a turbocharger. When all was said and done, they achieved about 90% of the list."
