TBH not quite sure about fuel mileage, never calculated that. I did this swap for reliability and efficiency.

MPG calculation would be to determine efficiency...

Did you get the startup thing figured out before going on the trail?

My idea of efficiency is no sputtering and hiccups when I'm on the gas ;D

Not yet...i know i mentioned before i have to dig deep into the software tuning but the cold start issue doesnt bother me as much to really have to fix the issue.

I'll throw in my update, sent the holley back after I found indeed, Holley desires you to use a single plane intake. I'm just not there yet to swap intakes so I'm staying dual plane carb for now.

I've been running the Terminator on a dual plane intake since November 2013. Add a 1 inch open spacer and it solves the dual vs single plane issue.
