Why am I getting better lap times in test drive?

I don’t use mods they will dirty a lap. Given the slightest of chances that I might beat my next rival.

Definate difference. I spent many hours tuning an S15 to drift with a wheel with 900 DOR and simulation steering. I’m talking well over 100 laps of Silvertsones shortest track. When I finally got to a standard I was satisfied with I immedietly went to free play so I could record a replay and couldn’t get it to drive the same after 18 laps. I had all mods off too.
