I finally got around to getting my NA mapped yesterday, Northampton Motorsport did an amazing job
Unfortunately the crank sensor bracket decided to crack and thus we could not get the maximum power figure, so we had to settle for about 15 - 20 bhp less on the day
However once a new bracket has been fitted the extra bhp will be available for me to use
As a guide: a Courtenay mapped 300bhp SC made 275 bhp on the same NMS rolling road
