Map 5 is an auto tuning map. That's why you are seeing different boost all the time. Different environmental factors such as ambient temp or heat soak will cause that. If you want more consistency try running one of the maps with a set boost target. With e85 you you may have to log and make some open loop fueling adjustments while on those maps.
