The only change I made from previous best was removed the filter element in my Fram canister fuel filter which validated a fuel volume delivery issue. Dropping .01 and getting + 2.51 MPH was great, especially for free!
Once I get a little more converter
(Redneck "Tight" 3500) and upgrade my fuel system
(-8 from cell to regulator) it should run low 12's! I need a better 60'!!! JD
P.S. ??? Unknown yet how the new combo will respond! Hopefully weather permitting I'll know by the middle of Nov.!
