FPRs and amm resistors

94 900T Comm Ed convertible. I have a redbox APC, 2.8 bar regulator and 30#injectors, t3/t4 hybrid turbo. I was planning on using an adjustable FPR to lower my static fuel pressure and a RRFPR in the return line to the tank so I could get the larger injectors to flow like stockers until I needed the extra fuel. The adjustable FPR raises fuel at a 1:1 ratio till about 10lbs boost, then the RRFPR kicks in at a 4:1 ratio up to max boost. I'm using this setup quite effectively on my Mopar turbo.
I've been reading a bit in the archives about the AMM resistor mod. I was wondering if this might be a better solution. Basically it achieves the same result by fooling the APC instead of doing things mechanically. If the AMM tweek is the way to go, how many ohm resistor is a good start? I couldn't find a consesus in the archives.
Opinions?
