      Excuse my ignorance but I'm confused. Wire tap is what adds fuel over stock. With out it it would just fuel like a normal truck? Because right now with our that part. it was fueling hard at WOT. Acting like it was getting plenty of extra fuel

      Had a good chance to test out my "experiment" today.  Drove out to eastern Iowa from NE Illinois today for a retriever hunt test;   and then back today.  With the E15 in my tank, my "Lie-O-Meter" is reading 20.6mpg.  Around 400 miles round trip.   Under very, very, similar conditions and miles last week on a trip to Tomah, WI and back to my place on regular 87 octane regular unleaded, my Lie-O-Meter was reading 21.8mpg.     The E15 lack of "Energy" is very noticeable going up hills and grades.............the Lie-O-Meter drops very fast when compared to regular E10.  Maybe the lack of energy in the fuel was enhanced by where I drove to today.  Once I get about 70 mile West;  it gets really, really hilly.................where the vehicles have to "work" to get up the grades.     I still plan to refill with E15 to get a more "unbiased" opinion...........................   Stay tuned.

      How did you figure your wheel bearing was bad, did it turn hard or sloppy. Did you change it then,

      I asked my rebuiler about the torque value and thats why you need the tools for torquing the 5th gear nut. I would double check my number but im pretty sure thats what he told me.
