my friend insany on tuesday,bone stock s13 sr20det with gt28/71r = 220rwhp@
4 psi...
looking at your graph @ djcobra your turbo starts spoolin hard at 3k, but hits full boost @ 4k....says it's 2 cents, then walks out the door at 4800, by the time you hit 6800, all the fun is over. hmmm

my RB25 , gt30/71r red = 13-14psi, blue = 20psi 93 octane 3.54 diff, pink = old tune 4.11 diff
gt30/71r on a 2.5L /w stock head/cams @ 13-14psi powerfc vs
28rs on a 2.0L @ 14-15 safc2 ....close comparison or no? in regards to turbo lag, overall powerband , etc
i will say though, being able to adjust timing definately helps. safc is ok, but powerband kicks ass with stand alone. there are things like safc2 or a
generic "this is my mods i'll send u my ecu, you tune it, i'll put it back in the car" that will get you by, but if you want the most out of your car's potential, stand alone is where it's at. and once you know what you want, and know your power goal, spending money on a good turbo is well worth it. just my .02
