Just so long as 87 is high enough for the APC to cope

If the 87 fuel is so poor that you are getting detonation even at base boost, there is nothing more the APC can do about it. Unlike the later cars with DI, the ignition cannot retard to deal with detonation. Perhaps the fuel system can dump a bit more fuel in to compensate (I don't know if LH2.2 can do that), but that's about all the car can do when faced with fuel below its octane requirement.
I don't know how old he is, but I'll bet he keeps his right foot planted to the floor whenever possible, like I did when I was younger. Come to think of it, I still do, and I'll bet I've got a good 20 years on him now...
Anyway, that sort of driving when detonation is going on will risk causing major damage. And with less boost available, he'll be keeping his foot down harder for longer to get some power out of it.
