If you're running in digital mode and laps are counting when you go through the ARC Pro powerbase on one lane, but not the other, then - as DrC hinted at - the chip LED and sensor in that problem lane are not properly aligning. If your other cars are good, then that alignment issue is unique to the GT40.
The most common cause for that sort of problem is a powerbase situated immediately after a corner, but if the guide to LED distance is longer than usual, then a half straight or more could still be an issue on the inside lane. I looked at this problem with the Scalextric Chevy Monte Carlo here: https://slotracer.online/community/showt...p?tid=1015
If this diagnosis seems about right, then one solution is to decrease the distance between the trailing edge of the guide and the LED. Another is to increase the distance between corner exit and the ARC Pro powerbase.
I hope that helps!
