The fueling will be fine got the Wolf controlling my 5th injector and yes I have a wideband controller to monitor the AFR's.

Dont really care much for top end power I hardly ever go there I will be very happy if it brings up the mid range. I think it will also help quite a bit with the low down torque especially below boost which will also be cool.

Ok shit yeah sorry forgot...

Ok so fitted the cam and changed the cam belt. No cam has leaned the car out by 1-1.5 AFR points (ie. 14.7-15.7AFR) which is a hell of a difference. Even with the AFR being leaner the car went pretty much like it did. I richened up the map to rather be on the safe side and it goes much better. I am not sure if there is much of a difference on the top end power but deffinately a HUGE differnce in part throttle and mid range torque. I can definately feel that the car pulls better on the freeway, when I floor it at 3000-4000rpm at 1 bar the car accelerates much quicker. I will be putting it on the dyno on Saturday to finalise the timing on fuel maps (since I fitted the exhaust manifold, bigger FMIC and now the cam). Honestly for R400 + cam seal + cam belt I am very happy.

Phinx the 7RwKw that you said is probably a good estimate on top end power but in mid range in far more. A top modification for anyone.
