Default FMU for 3-5 PoUNDS

i got a SOHC with a small turbo on it and im wondering instead of doing major tuning, can i just use a FMU for 3-5 psi? eventually it will be tuned but can i get by on 3-5 pounds with a just a FMU?

Yea you can do it and be ok but why waste the money on a fmu, just save a little more and buy proper fuel managemnt

if 3-5 lbs is all you EVER plan on running just keep the FMU. That's not even worth upgrading to a chipped ECU.

You can buy check valves at fish stores,auto places etc.Search ebay and classifieds for a used missing link they can be found cheap and are much cleaner and work better.
