glad to see you were able to experience the difference with the timing advance. its often hard to describe what the timing advance does but once you drive it you notice it right away.
Your gas mileage shouldn't be effected, except your now on the throttle more, in fact you should get better mileage as your running a higher AFR from the timing advance
Also resetting the ECU should not remove the timing advance. The only way it should go back to the default setting is if the system detects engine knock and retards the timing. which may also be the reason some people aren't even at 15 BTDC
if anyone is in the NY/NJ area I'm more then willing to meet up and do the timing advance for you.
