So your running 1 single -6 feed line from your regulator to ur carb? According to the fuel charts I have seen a single -6 line (3/8) is good to support 375hp, which when I was on the dyno and ran across my issue car was making right @ 380hp 400tq shutting it off @ 4500rpm's. How much power do you make on ur setup?
I also have a -10 feed from pump to regulator and a -8 return

i run two -8 feeds off the regulator the carb. my setup is apart right now. i'm deployed and am doing some upgrades. you had mentioned -6, that's why i said that. anyways, what reg do you have? i'd suggest an aeromotive 13202. it has 1:1 boost reference and is pretty much the standard reg to run on blow thru. others do work, but this is a very common and proven one. also, check out this sticky for a lot of good info on blow thru setups. if your a1000 is in good shape, just try swappin the reg and lines to -8 and see if that helps support enough fuel. i don't mean to say it won't work, i just had bad luck with 2 of them before and chose not to use em anymore.

yeah, that's possible. one was already on the car when i got it, so who knows what they did. anyways, let us know how it turns out. i'm sure going to dual -8's will solve your problem with going lean and emptying the bowls

i just recently completed my build and seemm to need some help. i have a stock 5.3 with a custom turbo cam .6**lift and changed the valve springs. i have a 78mm mp turbo,csu blow thru,350 tranny, 3200 stall and 3.73 rears with 28x10.5 mt's @ 8lbs of boost- i took the car to local test n tune and the best i could get the car to run was mid 11's at 120mph. i need help setting up the msd 6010 and i'm not using the map sensor. i got the timing programmed at 30* from 1000rpm to about 3000rpm then it drops to 18* across the board. please help!!! i know car should go a lot faster than it currently does. another problem i am experiencing is when i get on the transbrake and 2step (31/3200 rpm) and release it, the car 60 fts kind of strong but shuts down for about 1 second then comes back to life and takes off like a bat of hell. during that period of shut down i get black smoke. somebody help!!!!! i know i got a nasty set up and want it to run good throughout. thanks !!!!!!

I hold the advance steady through my idle zone as it idles smoother, this gets you a clean idle, off-idle with up to 42° advance under low load (remember, whenever your manifold drops to 0# or you go into boost, the MAP advance drops from 12° to 0°), and a boosted advance of 18°.
Another way would be to set up a "step retard" and apply 12v to the pink wire to activate it.
Here are some charts to look at and get comments on...
