I was told much the same in regards to the LPFP, so I opted to install a Precision Raceworks Stage 3 for piece of mind. From what I've seen this may vary by tuner as Halim himself noted that you could run straight E85 without the addition of upgraded HPFP's, but as Kratos mentioned in a different thread you run the risk of higher fuel pressure targets potentially locking up the injectors.

I'd imagine that the stock LPFP could be adequate depending on the ultimate power goal, but even PI requires the addition of an upgraded LPFP in order to flow well enough for high level E85 tunes.
Just watch logs for LPFP struggling and cap it a little short of that.
