EBPV delete VS MPG

[sldghamr]

is there a corellation between the EBPV delete and an increase in MPG's?? the reason that i ask is that a few weeks ago i disconnected my EBPV on my stock 96er. the first full tank i got 15.5 average MPG with mixed driving. now with the second full tank i got 17.8 average with the same driving. wtf??? i was getting noticeably lower EGT's and it wasn't as much of a dog when cold.

by the way, my truck is a 1996 F250 Ext Cab LB 4x4 4spd auto tranny with 4.10 rear. does the EBPV really cause that much difference?? any explanation would be helpful.

Yes there is because the EBPV is no longer closing and making your engine work harder
