As you have been talking with Fuji about all this, I do agree with him on the parts to provide better fuel, and monitoring. The DeatschWerks DW65C fuel pump is a great drop in pump that is designed to run 265lph on either standard gasoline or E85. You will also want to increase your injectors to run on the E85 properly. I also recommend changing the boost control selanoid for a GrimmSpeed Unit if you plan on putting it on the dyno to tune. Far as monitoring goes, fuji's suggestion of the true boost gauge is a great idea. We have also used the AEM wideband Gauge to help monitor the air fuel ratio. Let me know if there is anythign I can help you with.
