If the stock fuel pressure is say 40 psi (just a guess) and you plan on running 10 psi of boost, you should take your injectors out and get someone to flow them at 30 psi (40 minus 10) to make sure they are still atomising correctly otherwise fuel economy and power will suffer and you will probably find that you are maxxing out the duty cycle of the injectors early due to insufficient fuel pressure behind them.
