The trim screw is just an offset, will not comp for big injectors, but should help trim with big inj's and added 300 ohm R.
The 300 ohm brad type resistor is more of a global change, but not consistent % correction at low vs high output ( more rich at lower maf output)
Brad's MF2 2nd inj'r sys offers very good control. could use 4 inj's.

another way, if u have a PC ..
The linked conditioner is about $230. It allows u to modify a full MAF vs rpm 2D map (not same as LH map). Y axis is 0-5 V amm output, x axis is engine rpm. With 34# inj's at 3 bar, start with general 25% less MAF signal across board. Then go to the 5V input values at say 4k rpm, where amm 1st maxes out at 18+ psi, make it just 20% less. At 5k 5v cell, make this 15% less, etc. This way u are incresing fuel delivery based on increased air flow, beyond the point where ammm maxes out.
