add 5-7* timing = no difference?
my 1/4 time only went down 0.1 seconds and my MPH went up 2mph. boost,mivec.a/f were all the same from the last runHUH?? it dont makes sense.
That sounds pretty normal.
If you put a car/engine on a sensitive dyno, you can stay at the same RPM, change timing, and watch the torque increase get less and less as you add in more degrees of advance. Picking a timing value is about optimizing the cylinder pressure in order to make the most torque, safely. If you added 5 degrees, and you make no more torque, then it means your engine doesn't need the timing with the current mixture (e.g. air mass, fuel).
