I’ve only done a little testing just with different amounts of fuel. It seems like from my testing every 25lbs (4gallons) of gas less I have shaves .1sec off 0-60. Would be interested to see if your weight reduction shaved off .5+secs if you had any conclusive testing/data.
FWIW, the faster you're going, the less of a factor weight loss is to acceleration.
A more accurate way to isolate improvements due to weight loss is to measure 0-35 or 0-40 (redline 1st gear). The influence of rolling resistance and aero drag quickly take over after 25-35 mph depending on a few variables.
