Hmm, surprising... My manual 2000 GT deosnt have that problem and tops out at 225 KM/H (140 MP/H).seattlebrad87 said:I have a 2000 Celica GTS with the triptronic automatic and found out the other day that it has a speed governer and a fuel regulator that keep from going past 120mph. Does anyone know how to fix or override these or somewhere where i might be able to get help with solving this problem? Any help would be amazing thanks.
I think ur best bet would be the ECU - Maybe changing the chip.
Good luck.
