454 lsx w/ twin 72mm. Which FI to use?

[ssinister]

Working on a project that is going to be powered by a 427 or 454 lsx motor and twin 72mm nre turbos. Transmission is going to be 4L80E built for the power level. I am interested in what injection setup you all would recommend. We aren't looking for all out power numbers, more interested in driveability/reliability.

Both the engine and trans will need to be controlled. Have looked into bigstuff 3, fast, holley, would a factory computer handle this ?

Thanks for any info
