I'm not the brightest beet in the basket, I know. And I've not kept up on the technologies in engines. I thought EGR was on all gas engines. Is there a simpleton explaination of how they got away from EGR?

I'm thinking the loss of throttle response he is feeling is just the reduced low end power, he has changed the rpm at which the engine scavenges, which is the flow of the exhaust gas leaving the cylinder pulling more intake air in, there are waves in the exhaust that do not affect total flow of the exhaust, the amount of time the wave takes to go from the exhaust valve down to where it bounces off a restriction in the exhaust pipe and back to the valve determines when scavenging occurs, with the stock muffler system this is designed to occur at low rpms to increase driveability, when you change the system it can occur at a higher rpm, and with most aftermarket systems it occurs at much higher rpms than stock, correct me if I'm wrong about what I think you're feeling ittybitty
As our engines are SOHC, it is "hard coded" into the design of the camshaft.So there may be some system/controls that will put/leave exhaust in for re-combustion?
The Ford system is quite a bit different than V-Tec. Ford (as well as most other car makers) uses "phasers" that use oil pressure to advance and retard the cam based on rpm / load. At low rpm, the cams are retarded for better low end power and economy and as rpm rises the cams are advanced for better power / economy.The 6.2L has variable valve timing, this is used specifically for exhaust emissions, not performance like the little Honda's cute little v-tec, I'm not sure exactly what it does {snip}
That was a general comment directed at all who were reading this thread, not you personally.Lmao, don't get butthurt and read only what you want to believe I'm saying instead of what I really am saying kaiser, if you knew how to read you'd know I was saying that the ford system IS NOT like the system used in Hondas, get over yourself, I know ford uses oil phasers, I know what ford says they do, and I've watched the phasers actually work on a running truck
Really? All I have provided is technical info. I have not questioned anyone's ability to read, called anyone butthurt or told anyone to get over themselves. I am not butthurt (I see nothing in my comment that would indicate as such) and I read very well, thank you very much (this is the second post in which you have questioned it)....get over yourself....
