Win 10 w/ FO2 Ski Jump ...I've put some serious time into playing this game!! I think that, 'Afterburner' car, is best for speed, gowever, on some days I can hit 119+ mph @ launch, doing it over and over. Now, I can't even seem to break 110 mph?? Why would this kind of wide variable with my top speed be happening?? I'm using this same car every time, very curious about this. Please advise.

Thanks a million!!
