Is there a difference in the BLACK and BLUE top vortech FMU"s?
I'm about to trade a member for different ratio fuel disks,
Would a 8:1 off a blacktop Vortech FMU fit my blue top Vortech FMU, or are they two completely different designs?? This board is great

The old GReddy ones with the black tops were 10:1 I belive, the blue ones that come in like DRAG kits are 12:1, but aside from that, same thing.
