I had this exact same issue and it gets really annoying. But make sure you set your overboost to 18.0 as well because with the E85, you will hit that much boost, well depending on your mods
The map (assuming you are referring to map 5) is what governs the boost...it is possible to over boost to 18 though. I had the code above and just cut back to 45% instead of 50% and there is really no difference in performance. I may go back to 50% but I only get these codes once in a while so not Thst big of a deal.
