It makes sense. Higher pressure requires more work by the solenoid to open. Does running at 4 or 5 bar offer a measurable advantage for naturally aspirated engines?
Plus, you'll still need to create test bed to figure out the dead times if you can't find them published somewhere. One tuner told me that they prefer using the actual ECU to develop dead times not just a voltage range. That seems a bit over the top but I guess with high end stuff, you can't be too accurate.
