This is what I was thinking. He could have just had a faster car to begin with, but wasn't running it to its full potential. Hell, I was running bad times at first, then shaved off about .6 just by driving it RIGHT. Then I upgraded my exhaust and got some lowering springs. While my launches were smoother and a bit quicker than before, I only picked up .1 in the final ET.
