gus you know as well as i do that untill you get your truck on a true dyno, dynojet 248 that 807 is going to get called bs. just like in the other thread where i stated that winslett has the vp record you said i was incorrect because he to was not on a 248. same has to apply to you. if you got on a 248 and made over 750 on fuel i would be sold. but the fact of the matter is no one has proven the pump makes hp over a so pump or hrvp on a 248. everyone knows thats the diesel standard dyno. another thing i have yet to see is if electronics make any difference with these pumps. i have heard mixed stories about the pump not responding to boxes due to the pump already being maxed out and so on. just my $.02
