eos switch has nothing to do with the maximum position a flipper can achieve !

Maybe the coilstop on one side has worn much more, so the plunger can move further.
Another possibility is that one of the flippers has been rebuilt with another type of base plate, plunger type or coilstop.

I thought he only reproduced the strobe driver board (that goes behind the backboard) and not the strobe light itself ?

Almost never. I prefer to work towards super jets.

Made a cow abduction mod for AFM.

When I bought my AFM the bumpers were all 3 broken and didn't register. I noticed this changed behaviour of how the scoop registers and did certain awards.
Don't remember details, but the game seemed bugged because pop bumpers switch hits never changed. Probably the game has a counter on it in relation with the scoop.

So check if your pop bumpers work correctly, and let the ball hit the bumpers before entering the scoop from above.
