OK, no one got this one? Sounds like detonation to me. You need to run premium in these VHO trucks at all times. Also get rid of that Granatelli MAF, I know for a fact that does not help.

If you look at the Octane rating in the owners book I think it says Premium only.

Indeed it does. I think it is on the dash and the gas door also. The other problem is that MAF, they tend to lean the mixture out....that is how they get the 5-10 hp they "claim".
