Well worth chipping and having it setup correct IMO, not massive peak gain but you will be seeing around 5-6bhp gain at point on the power curve, much sharper pick up, sharper throttle response, smoother torque curve and much stronger WOT conditions across the whole rpm range which a higher rpm limiter.
We charge £20O for a custom chip tune on our rolling road, if after the tuning you feel it's not worth the money or not what your after you don't have to pay a penny.
I have many happy customers running an RTech chip tune and they all seemed to be happy with the overall results.
