Sorry, to clarify, the shop that said no E85 unless stock and no FI at all was the one that quoted 220 as the max.
Definitely understandable that it's really a toss up at the moment, but on all stock internals, all the other shops seem to be saying 300-330.
I've been following this forum for quite some time (since it launched YEARS ago), but haven't become a member yet. I've seen all these other owners crank out 300 and run E85 without problems, so I was a bit confused. Just wanted to know if there was a consensus among the forum members. Seems to be around the 300 mark as well (without stronger internals).

spitfire481 Having mentioned you held them in your hands, what would have to be your educated guess? (not discounting everyone else, mind you)
