what has worked good for me is to;
1 put in new spark plugs right before you go
2 change the oil right before you go,I read that if you have old oil in your car that it will have a slight amount of gas in it and you hg will be higher
3 make sure the timing is right on were it should be
4 use 87 oct gas less octane means the fuel will burn all the way (just for the test go back to high octane after that)
5 if you have to were your pipes go over the axle put holes in the top of the tube then get it fixed right away(I know its not the best idea but it works)
please don't nail me to the cross I'm just sharing my info
