[QUOTE="Marty, post: 203646, member: 602"] I just got done recording the pressure drop on another truck. 2000 f350 dually on 35s 38r / 1.15 housing International uppipes Martys fuel system Swamps 175/146 Swamps tuning, highest tune for 175s Graphs are at shop, don't know how accurate they are because the map sensor hooked into intake was reading 14.4 at idle. The highest drop i recorded was .52 psiA at the end of a long rpm pull in 3rd gear. The normal was .2 but it was certainly jumping around more then the E99 truck I posted above. Reason I don't know how accurate it is, is because at idle if you would floor it it would drop to 14.3. Unhook the line to the intake and floor it, it did the same thing. I plugged in another map sensor and it did the same thing. I will post the graphs when i get back to the shop on monday. For the record this truck pulls the filter minder in everyday, even on a brand new filter. This particular truck has less then 1000 miles on the filter, BUT it spends its life in a rock quarry.
