Well i have done it and got a ecu,turned up this morning and i fitted straight away

Started and warmed up spot on the when i took it for a drive you could feel the difference from the off pulls harder and boost's to approx 14.5psi(not got a very good gauge) It has cleaned up the hesitance i still had as well.The guy i brought it off was only running a back box and filter,he had the dyno with this at 260.So i hope mine is doing about the same just got a decat downpipe so may be a little more to came
