You live in Savage? Where at? I haven't seen this car around yet. Also you called me Swanny...what is your name? Odds are I know/recognize you but not the SN.

1680's should not be tapped out, plus I doubt that DW300 can support 1680's @ that boost pressure, you may be out of pump. To gain flow, you will have to scale back the baseline fuel pressure AND supply more voltage to the pump, hopefully the FPR can keep up. I am assuming your baseline is 43psi +30psi = 73psi gauge. If I had to venture to guess that would be around 225LPH. What is interesting, is per the above chart, you were only flowing maybe 200lph previously.

I would suggest to pull the baseline back to 30-35psi gauge. That will put you around the same flow now (little higher technically, maybe 20 more lph) at up to 35psi. Gives you some headroom.

Of course you are shrinking the injectors roughly 16.8%, making them 1397cc @ 30psi baseline fuel pressure.
