The AMR Pro has 1160 hp stock irl (according to aston themselves) while the fh5 variant only has 800. Additionally the car is around 150 lbs too heavy stock. Both the stock power and weight nerfs are alright, because it needs to stay s2 stock. However, there is no reason whatsoever to at least make it so the car can reach its irl stock power and weight through engine upgrades and weight reduction upgrades. FH has shown in the past that it has had no problems in the past making super op cars in x class (fh4 599xx evo and fh5 sesto fe), so theres no reason to keep this car nerfed even maxed out.
The car can reach the higher power level through removing the restrictor plate in upgrades:
I got that part but it has 1160 irl but only gets to 1000.
I’m pretty sure that’s only because the engine itself gets to 1000 hp, the 1160 hp figure is just with help from an electric motor, which isn’t always active
edit: I don’t even think the amr pro has the electic engine to help, so 1000 hp is completely accurate
