I believe no companies out there currently source an upgraded HPFP for the N55, I could be wrong though. I am flashed with MP stage 1 and I normally just fill up 3-4 gallons of race gas plus unleaded octane booster to bump up the octane to roughly 95, better to be safe then screwing up the car I guess... lol

Now you have me nervous running 2-3 gallons (roughly 15%) E85 in the tank as frequently as I do. I don't seem to have any misfiring issues. From a preventative maintenance standpoint, I plan on replacing my plugs and doing a walnut shell blasting at 50k miles. Anything else recommended since I'll be running a JB4 and 2-3 gallons of E85 fairly consistently?
