I was also gonna suggest you ask Flaco about what he'd recommend, never met him but he seems to know a thing or two about FI

Ok, what i've seen with my truck is with bigger motor 416Cid i got more power than the 6.2L motor. But what i didn't understand when i changed the motor the boost droped from 10PSI to 5PSI while useing the same old pully, even tho i got more power even with 5PSI.
