And for reliability and simplicity reasons I prefer oem throttle bodies.  (Forgot to mention in my thread I installed a new oem on my motor).[ATTACH=full]484968[/ATTACH]Ford’s continued the use of the same HL3Z intake manifold and TB since 2017 gives me confidence. They even back-updated the same HL3Z throttle body to the gen1 Ecoboost in the transit.  Fact is the 3.5L charge air side is well executed (i was told roush did the charge piping design work for g1, g2 and g3)[ATTACH=full]484967[/ATTACH]If I thought there would be free-lunch gains like with the intakes, I’d be running oversized tb on my own trucks tonite. A larger set of camshafts may change this, I hope to find out.  Reliability in a truck remains paramount in my opinion</blockquote>
