turbo injector help

I need advice as it is my first time with honda....I have a b16a eg6, installed a turbo from a nissan skyline rb20. It is a strait t3... i think, exhaust manifold fabricted, intercooler from an evo3.
Right now the car really feels much faster. My question is fuel enrichment. I am just running 5psi of boost and the injectors I installed flows at 280cc as compared to the stock 240cc injectors plus I raised the fuel pressure to 45psi from 38psi (with vacuum connected) Since right now I dont have access to a wide band o2 sensor or similar I would like to as your opinion if these is enough fuel enrichment for my set up. Right now the car is kinda rich at idle and low throttle but I dont really care, whats important to me now is during boost that I dont get too lean
