I uprated my wastegate actuator from the 6PSI unit I found under the hood to an 8PSI version. But I am now considering trying a 10PSI version. However, not being in the picture on these things as clearly as many others, what are the potential problems that I could face? Should I perhaps also consider uprating the BPV/BOV? Someone advised that I go for the re-circulating type rather than the blow-off version. Any professional advise outhere to stop me from blowing my engine up?
