Not to nit pick you dantilla (ok, I am nit picking) but the fact you knew the chip was switched did introduce some possible bias. You may have subconsciously felt that with the "newer or better" chip the car would perform better. This could have led to you driving more aggressively and have a lower time. Sort of a different version of a placebo effect.

If you had driven back to back without knowing the chip was changed that would be different. Not looking to pick a fight- just bringing up a point. Randomize it and double blind it and then we will know for sure.
