Drives much nicer I need a proper induction like BMC as the k&n pannel filter and drilled air box is kind of strangling it So like this it produced 210 bhp but I was never interested in the figure I was more concerned what it did on the road tbh It revs to 7200 now so makes more use of the cams and is also much better on fuel and a lot more responsive on the throttle But figure wise wasn't helped due to the fact it was mapped in hot weather but can't help that
