cool cheers man,what about the boost is this ok? someone suggested it might be to low for my car or would problems 31 and 45 be enough to drop around 80/90 bhp?

Do an ECU reset,these might be "Historical" codes When resetting the ECU if the MAP and TPS is guffed then it will flash a fault code at you during the reset
If the TPS is guffed then the ECU wont be seeing a maximum throttle input hence it wont produce maximum power Also the MAP sensor wont be giving accurate signals back to the ECU another contributer to not reaching maximum power Fix both these problems,reset the ECU and retry it at the RR you should see a figure of circa 200bhp at the wheels which would equate to roughly 260bhp at the flywheel
Good Luck
