With the profec e-01 you can control your ignition/fuel maps...
Not sure how you do it with e01, but with the software you just input your old injector size and your new injector size and the unit will auto-calculate the new MAF voltage for you... be aware that changing injector size on the blue emanage will alter your timing.
Also, when you are adjusting injector size, make sure that you adjust it in the "additional injector map" and not the airflow map.
With 370ccs and @7psi, you can probably get away with backing your distributor 3-4 degrees and just tune your fuel map with a wideband o2.
My setup is 550ccs with fuel/ignition harness. I retarded timing by 5deg on distributor and added/remove timing on the ignition map where I saw fit... I also modified the additional injector map to add more fuel under boost to get 11-11.5 a/f, all street tuned only with wideband and my laptop.
