Having to buy two FPSS, and two fuel gauge senders, uhmmm... cost?
I think it'll make up for it when it reads a little lean on the dyno and all I have to do is up the pressure a few pounds...Or when I can run close to stock timing with c16 in the cell on larger hits...

You might not have to buy those when you stand alone...
think thats about it.
$$$ for a standalone, is cheap insurance if you have tons of money wrapped up in the engine.

cost and slight weight penalty are the only downsides imo

the main downfall i see is that if you dont run a FPSS and the fuel pump in the stand alone dies kiss your motor goodbye. unlike if your main pump fails the car will lean out for a second and then basicly shut off.

the more complex a system you build the more there is for the chance of something failing. thats how it is with anything.

umm only downside i can think of is if your like the guys local to me, you wire it up seperate from the nitrous, and forget and just turn on the nitrous not the stand alone...
now if your like me and the stand alone has to be turned on to get power to the nitrous then i see no downfalls, dont run it low, and the only problem id see if initial cost
