Mileage: 42,000 miles
E85: 19,800 miles
Also, does anyone else notice that there is less low end grunt/torque on e85 compared to gas? Or is it just me. I am using off the shelf OFT tunes.

No problems, drives amazing and smooth. Flex-fuel Ecutek tuned with several revisions for a little extra perfection.
Unless your tune is not well optimized, it may be an odd feel you have for the way the car now accelerates. One of the things I noticed is when I'm not running E85, The pull post 3.5-4K RPM is very strong and really makes the car feel like it's coming alive. This sensation kind of goes away when I'm running on ethanol. I think much of this is due to the change of the curve, with the lower end torque actually being quite a bit stronger, making the overall torque more even. This "evenness" doesn't give the stronger pull sensation, but rather a more simple acceleration feeling. Regardless, the car is much quicker throughout the full rev range on E85, but the feel of acceleration differs for sure and in some way it bugs me a little too. When going back to 93, I enjoy the feel of the pull post 3.5K RPM. E85 just doesn't have that same feeling as it is already pulling pretty good from lower RPM's.
That's just my thought on that. Again, it may also be that your tune isn't quite up to par, and of course, your tune could be optimized differently in general. I'm not too familiar with how well OFT's tune is on E85, but judging by the dyno pulls I've seen from OFT, it seems pretty good.
