Its hard to read a alky plug, from boarder line "rich" to boarder line "lean" the plugs look the same to me despite what EGT, or MPH says.
When you find out let me know...
here is a bump for ya..
I can tell you that with lots of squeeze and on alky, plug gaps doesnt like to be much wider than .035
I get the tune close, and tune for MPH the same way I do on gas.
When your close it will gain about 8 deg temp from launch to cross the finish line..You gotta look down fast, cause once your off the throttle the temps will fall fast...
I try to stage the car at or near 160..
