FP with DSM 450s?
Sorry if this has been covered, but a search yielded nothing. What fuel pressures are you guys running with your DSM's? Mine are going in this weekend, hopefully.
wait a min... are u running a s-afc??
if u are, u can leave the fuel pressures the same and use the afc to tune the fuel down.... otherwize, u'd have to mess with the fuel pressures big time. Its not a good idea to run 450's on a motor without at least using a s-afc. Playing with the fuel pressure is not the right way.

Yes, I'm running an AFC, and it's going to be setup a la the "hack", -40% fuel trim across the board. I was asking what fuel pressures people who are running the AFC hack are using. Sorry for not making that clear.

stock is like 38/45, right? I just did the install last night, and it seems to run pretty well, with a little hesitation if i let off the throttle for more than a couple seconds.
got this from Hondata:
High horsepower boosted cars often need large injectors. Most large capacity injectors are available in peak and hold form - about 2 ohms impedence, whereas most stock injectors from about 92 on are saturated (8-10 ohms impedance). Honda engine computers require a total injector impedence of about 10 ohms so a resistor pack is needed whenever the stock saturated injectors are swapped with peak and hold.
my set up idle 24psi on b&m regulator with hack safc running on dsm 450cc injectors. Runs perfect all the rpm and even in full boost 9psi.....
