You make my decision for 240V PID HLT and 110V PID RIMS a good one.
Is the gas valve proportional or digital (on/off)?
You could size the valve (referred to as orifice size) larger. Would assume you have a 1/4" valve body in there now - $50ish to go larger, say 1/2" body. Did Blichmann add any additional orifices to the system?
