FiTech EFI system

So you bought the 1200hp unit? Probably best incase you upgrade at some point.

Did you already have a fuel system to support it or did you need to upgrade that as well?

What CI is your engine. Any details?

I got the 1200 hp unit because I am running e85 on a 416 sb, that Mike at MRL built. It dynoed at 650 but the system was an accel and the engine never did right run with the Accel.
My fuel system was already capable of supporting it.
