I never said it wouldn't help or it would hurt anything, I just said it wasn't necessary. Just like it wasn't necessary on the 400K mile 2.7 Ecoboost on the f150forum that is still running strong.They're not necessary.Just keep in mind the engineers were forced to feed that blow-by crap back in to the intake. They didn't do it because it's better for the engine. They did it because it's better for the environment and they had no choice. They also design the vehicles with catalytic converts, not because it makes the engine run better (quite the opposite), but again, because they were forced to.
They also didn't equip a lot of vehicles that have the same engine as the Gen2 Raptor with twin turbos. Why? it's not necessary for the engine to have them, but it sure performs a hell of a lot better with them.
I don't agree with your assumption that if the vehicle needed it, the auto manufacture would already provide it, especially when it comes to after market devices that make it run better or last longer.
The Gen2 Raptors don't NEED twin turbos, but yet they have them ... and the truck cost more and performs better than a regular F-150 because of them.
