[QUOTE="Hotrodtractor, post: 263950, member: 25"] I do believe that the validity of the testing and the 1 second reduction in track times is what is being called into question. I understand what a PITA it is to pull a cab to swap these components to do dyno runs on the same truck - but what if we were testing something else... say some custom tunes... Is it acceptable test procedures to run Tune A on one truck and Tune B on a second truck and then compare the before and after numbers with certainty? What I am getting at - do I think the SteedSpeed manifolds have the possibility of producing more power over stock? Duh. No brainer, that is a yes. Do I have a real good feel on what increase I might get? Not really. Also - I'm not sure why SteedSpeed elected to not take Dockboy up on his offer since SteedSpeed did say that he would put money on it that his manifolds would increase power and torque. Big deal its on a Cummins instead of a PSD. I also think its a bit outlandish to think that SteedSpeed is only marketing to the Cummins crowd North of 1kHP and not any "daily drivers" - but yet over here in the PSD world the testing was done on a pair of stock turbo'd trucks (or at least based on stock turbos) - why would a company go after a high end market share on one engine only and then go after the average guy market share on another engine? Just playing a little devil's advocate here. No dog in this hunt. [/QUOTE]
