Default 5 bar fuel pressure regulator
Would upgrading from a 4 bar to 5 bar fuel pressure regulator improve or degrade performance
on a KO3 running a 1.2 bar chip?

Thanks in advance

Default well, you'll run rich all the time... so... you'll have really crappy gas mileage, and running that
rich you risk doing damage to the catalytic converter.

Default i forgot you have a crapload of stuff. you might benefit from a 5-bar FPR with the T28 ...
ask audi2ptzero - he's incredibly knowledgable about the T28 and just about anything else.
