Hi cohiba , good of you to post up. and glad its back to full health
Im v surprised to be honest , your 267 bhp graph seemed to flatline
does the awesome graph look the same in terms of shape?
Either you had a problem and its gone away , or you never had a problem and Proport had problems getting a reading.
wonder if theyd give you a free run to check

Has the car felt the same throughout all of this ?
enjoy the car , I think there was universal concensus the APR exhaust sounds the nuts

it cant be whp from Propsort as that would be crazy numbers. its flywheel corrected bhp
