When turbo'ing my 3SFE engine, what if I use a 2:1 rising rate fuel pressure regulator to help correct fueling for the increased air flow.
With a 2:1 RRFPR, the inline fuel pressure will increase by twice as much as std as boost increases and the regulator sees boost pressure. So, effectively, the 32psi odd will increase to 64 psi odd at 1 bar as the increase is linear. |

in my early 7th gen celica turbo kits i used an FMU. it was more like a rising rate. so it was not always 2:1 it was rising. we then used a split second to pull back on the fuel in boost. it worked well.
