The motor makes no difference on return/less as the computer and fuel system does. If you have a 255 pump and are using the 02 rails/system then I could forsee issues. If you use the tank, lines and fuel rails from a 96 or 97 gt then you can have the TRUE return style system in a mod car. The 98 I built is a hybrid year, uses return style lines, rails, but with a voltage regulated returnless style pump. We burned up a focus pump on the bottle and got lucky not to melt down a piston, so we ended up re wiring the pump with a simple painless wiring kit for an old style 255 pump. (we also swapped in 97 rails so we could put an adjustable regulator on since the 98's was built into the rails) The car was pig rich (actually had fuel) the only time we got it to mokan then we shattered the rear end the 3rd pass.
So I guess I would be curious as to which factory set up you have, fox body or the 02?
Rogers is very close to me yes, Check out (sorry mods if I can do this)
www.100mphclub.com. Its a local site (based out of Joplin/Springfield) that gets together multiple times a year and does a mini version of the hot rod power tour during the summer for some good times. We have a lot of NWA users as well.
Anyway, the florida 5.0 cluster is my suggestion and how I planned on swapping a mod into a fox (before I got the deal on my cobra).
House of Boost is in KC, MO. There are a few tuners in Tulsa and Ok City as well. Also Gearheads in Dallas seems to be a good place to go. We ran a "mail" order tune from vmp that was GREAT on the motor but ok on the bottle. was SUPER lean when we put it on a local dyno (caseys road and race, in neosho, mo) but I think it was the fuel pump issues more than the tune that made it lean.
