I'm not sure about power, but feel wise about the same has what it was, I don't think the injectors can cope with what the turbo is asking of them either that or the map is rubbish so need to speak to the garage on Monday...
Basically its fast has but if you give it some and stray up to and past 4.5k rpm the ecu goes into limp mode? stop turn off and back on and its fast has again.
Ill be going down to see Paul at RST once I get time and some more money, I think in essence it is very fast but It needs live mapping not a generic one which is on at the moment.
