Yeah, anybody who says an FMU is a viable option anywhere, needs to grow a ------- clue.

do FMU's install on the feed line to the injectors or the return line?? cause i read somewhere that it installs in line with the regulator on the return line..but someone said that it installed between the filter and the fuel rail...

Yea. And I guess you missed the fact that not all cars have the option of an ECU hack like you honda OBD0 and OBDI folk have it. No one has cracked the code for my car yet. So the one of my options do include a FMU. Six additional injectors sound great. But not very easy on my intake manifold setup.

fmu works by increasing the pressure
you could put a bit bigger injector but it would ---- up your idle and normal driving
if you cant program the ecu pulse with and you would have to changed to a lower ratio
instead of running 10 to 1 you would try 7 to 1 fmu

ive tried 330 cc on my gsr 4 year ago and it would run under boost it would flood it
and the stock gsr were 240cc

All engines are basically the same even if the electronics aren't. Fit a different ECU.

Might as well go with a stand-alone ECU. Either way, I'll have to redesign the entire engine's wiring harness.

But not an impossible option.
