I was able to get 34 this time around with no knock.

I guess i will just wait for my second tank of E85 and raise the boost.
and a retune..

 

do you have any exhaust rattles ... you could be getting knock signals from that

 

If your E85 tune is done correctly - with fuel and timing tapered properly - you should definitely be able to turn the boost down without getting knock.

I always take it easy with the first tank of either E85 or gasoline when ever I'm switching fuels. If this was on your first tank, I would simply wait and see what happens on your second tank.

 

Thanks that is what i am going to do.
about 2 gallons gone now and exhaust noise is slowly going away.

 

All problems fixed.
37 psi no knock no exhaust Bah Bah Bah.
runs smooth and strong and ready once again for the track.
