Some would beg to differ on that as well. He should be able to get away with using it for awhile. I would highly recommended no matter what you chose, monitor fuel pressure at the rail have a wb and data log imop. Without a proper tune or data your in for one hell of a time
Thats because some haven't seen enough walblow's fail with E85..
Their junk ... Too hard to tell the real ones from the imitations
Why chance it .. For $145 the DW301 is the way to go !
