thats what its limited to by actuator/ecu normally. I'd say 1.5 bar maximum safe before stalling. what are you trying to do ? remap ?. if you know the turbo, look for a flow map for it. It's perfectly adequate for big remaps.
bolt it on the 1,3multijet! 130hp as target.also new airfilter, Larger front mounted intercooler, reinforced clutch. have all the bits laying around! injectors should be fine, and i think i need more than 1bar of boost to get to my target.
