Do i need an FMU with a tune?

My supercharger came with the FMU unit. I want a tune and was wondering if i would just remove it and the tune would work without it? I assume this but i haven't seen it written anywhere.

you would need bigger injectors if yu want to ditch the FMU

Agreed, larger injectors would typically be needed, but in my opinion, this this the much more prefered method anyway. Even with 6-8lbs. of boost, a good quality fuel system, larger injectors (usually around a 42lb. on a 350ci motor) and a quality dynotune makes the drivability of the car so much better not to mention some perforance gains as well.

My injectors are factory with 108K miles. What would i want for brand and size for my setup? 42lb sounds big but what do i know.

I'm running 42lbs injectors and no FMU also.

A "larger" injector won't cause any problems as the PCM will turn it on only for the length of time needed by lowering the duty cycle. 42lb. injectors are typically a good choice for your application and they will give you a little room to "grow" as well. I ran these in my 350 ci motor with 10lbs. of boost and the drivability was fantastic.

Is there a brand or type i should get. I guess the 42LB will be the size.

Bosch green-tops are nice.;)

There is a guys selling some 60 pd Mototrons in the For sale section for $300 which is a good deal on some killer injectors that are plug and play with a tune.:)
