When using the 100hp tune on my 2004 F-250 the throttle surges at almost any speed. Since I have had this problem I turned it down to 60hp, and that seemed fine. However, at hard acceleration between 3-4000 r's it really starts to pulse. Any help would be appreciated.

we have this complain before and will like to duplicate here in our facility to try to fix it, being a 04 you most have a vxap1 or 2 hex familly , for now make sure both off your fuel filters are good and we are looking in to the problem
