OP should check his jetting for the source of his heat. And with 11:1/stage 1 I'd think a 2:1 pump to race fuel mix which nets about 98.67 would be more than enough if he's getting some ping.


Photobucket is trash now, use something else.

Your engine tune has nothing to do with the smell. If the aromatics are in the fuel it will smell the same whether you are rich or lean. You either bought a different version of fuel, or got ripped off.
