You can run as much boost as you like as long as the car has been mapped correctly.<br><br>The problem with the FRST is that the map sensor runs out of calibration at just over 1 bar - this means that the ecu can tell if you are running 1 bar or 1.5 bar.<br><br>Normally tuners make the car run quite rich over 1 bar and set the max boost on the actuator.<br><br>Ahmed Bayjoo does a mod where he fits a 2.5 bar map sensor from an escort cossie.<br><br>This only works with the early ofab ecu though.<br><br>Hope this helps<br><br>Mike
