So I am using the Diablo sport predator tune that came with my Supercharger as a base tune. So it is not adjusted for the cam that I'm running.

According to the tune, they quit adding more fuel at 4800 rpm. My question is, now that I have adjusted for the fuel on the high end, do I need to change the spark timing more to maintain a rich mixture? My afr shows that around 5000 rpm it starts to lean out. It gets leaner then 15 at 5800 rpm. Any help and input would be appreciated. Also, do I need to adjust the pulse width of the injectors to accommodate for the higher lift and longer duration?
