Before someone says "you can't use 1g dsm injectors"... I'll reply, yes you can! You have to modify them though. And they also run very hot and use much more voltage and aren't so great for the ECU... but they can be used. I don't recommend using them for daily driven cars for this reason.
RxR- Sorry there's no exact answer to your question but you better have an S-FMU if you're going to ATTEMPT to tune these things. I use them but they're hard to tune w/o an S-AFC. Try setting you static pressure in the low 20 psi range. Use an accurate A/F and EGT gauge and use a datalogger. You're going to max out some fuel trims too.
Oh yeah, 450cc is WAY OVERKILL for 6-13psi! You need injectors between 310 and 390 cc for your setup. I'm sure you bought them cheap but they're not easy to use!
