Lets ASSUME for our example here we have a TBI setup with 2 80lb/hr injectors and a MPFI setup with 8 20lb/hr injectors (This will make numbers easy )

Okay so again ASSUMING we give both systems the same net increase in pressure we can easily find out the extra flow.

(Since percentages are out of a 100 it is import to divide our figure of 3% by 100 to obtain .03)

20lb/hr*.03 = .6 <-- This means that we will gain .6 lb/hr per injector
20.6*8 = 164.8 lb/hr

80lb/hr *.03 = 2.4 <-- This mean that we will gain 2.4 lb/hr per injector
82.4*2 = 164.8 lb/hr

WOAH!!! this is of course assuming we give each setup the same increase in fuel pressure from factory which we can give the TBI system a larger increase since it was setup to run from 15-18psi.
