Just because an engine can rev higher, doesn't necessarily mean it'll produce more power. Granted, stick a hot cam in the motor and lightened flywheel and you've got yourself a revvy little engine with lots of top end poke.

And my napkin holders may well be 1 offs because it was a scrap piece of metal at work that I used, the end of a stainless bar that would otherwise probably go to waste.

As for a DIY PCB, I can't see a picture of the mods PCB on there, only ECU PCB's so without seeing the mod itself, it's hard to say.

As for working in theory... Yes, it is known that changing the crystals can affect the rev limit, but there are other things to think about like the fuel cut off and whether the ECU will like the new rev limit.
