Its on 1bar at the moment, but my mates evo 8 is on 1.5 bar and its bloody quick. The forged pistons must be able to take some serious boost though right? What is the maximum boost i should set my car to?? I have a stock engine

 

i had mine at 1.3bar , all standard on apexi fc ,but done a head gasket, not sure it was the extra boost that caused that, set up by A FORREST (330 bhp)

 

anything above stock limit would need remapin, my00 stock limit was 1.2 bar
