[QUOTE="Erikclaw, post: 444840, member: 661"] Was floored from 20mph? It is impossible to compare results and say they work if never had them in the truck, then do a single, injectors and manifolds all at once. We know they work, just are they as efficient as what is already out there? Mike knew at what rpm the 6.0 manifolds spooled, and now it does at 300rpm higher. It is a fact that his truck spools slower and is down on power. It is hard to compare when you have nothing to compare them too. [/QUOTE]
