too much fuel means less hp and more cylinder wear. many haven't a clue how much they run.

total stock set up will continue to supply more fuel with more boost per ecu maps, although a bit lean. mabe 180 hp at 2.2 map limit or inj saturation. mabe more range for 2.4.

1st level upgrade ... just add 3.0 fpr or ford 24's to get 10% more fuel, 180-190 hp basically stays in original ecu map range, 12 psi at top end.

2nd level ... want even more fuel for more boost, but still with accurate control from ecu, based on amm signal. enter split-sec.com signal conditioner for amm, to be used with bigger inj's. allows bigger inj's to be used with properly reduced amm output, to extend the range of air flow based fuel control by ecu. Brad uses a 300 ohm res with 2.5 fpr and 30 lb for lh2.4 (if ford inj, actually flows 31-32 lb).

brad usually uses resis with lh 2.4, but same principle works with 2.2, which has an added screw to trim idle and low load mix. Best to check tune on dyno with wide band sensor.

water inj allows less fuel, but still want controlled flow.

3rd level ... around 220 hp with this method, u hit limit of inj saturation, or max flow for amm. could then kick in high fuel pressure or 5th inj'r for more fuel.

imho, holding 20 psi is abusive, and more power at 16 psi with upgraded turbo and IC.
