After running B100 for the last 2 years it was time to think about advancing the I.P.
Today I advanced it 1/8" and noticed it still smoked when I first started it, but not as much as before. After it is warmed up the smoke stops during normal driving unless I floor it in park. When started hot it gives a small puff of smoke.
The question is will the miles/gallon increase.

 

By advancing the timing 1/8" most people gain 1-3mpg, depending on your driving type. With quicker throttle responce its hard not to take off faster.
