unfortunately no. Not an FMU.
These would be FMU's....

Re: is this considered a fmu for turbo? (leed)
im kinda new with turbos...im working on a turbo kit my self and i always wondered what the purpose for the fmu was ..does it replace check valves?,or is it a cheaper way to go instead of spending the money on a hondata,aem,uberdata ? ive asked friends who know lot about turbos and they had no idea what the vortech fmu was?...sorry if this is a newb question on this subject ,but im trying to expand my knowledge on turbos

Never ask these friends <U>anything</U> technical again...ever.
FMU = Fuel Managment Unit
The acronym is thrown around a lot, but typically refers to a fuel pressure regulator that has a manifold pressure reference on it. It raises fuel pressure in mutiplication to manifold pressure.
Typical 1:1 pressure regualtor in boost:
10psi of boost pressure = 1 x 10psi increase over base fuel pressure
(10psi increase + 45psi base = 55psi of fuel pressure @10psi of boost)
12:1 Vortec FMU in boost:
10psi of boost pressure = 12 x 10psi increase over base fuel pressure
((12 x 10psi increase) = 120psi + 45psi base = 165psi of fuel pressure @10psi of boost)
Now, you see why people are getting out of the pump/FMU setup? 165psi is a lot!
