Good post David.

The Thing I want to make clear as to help you guys is that in changing Cam timing you are changing the running compression of the engine. This means that the AFR and timing settings are no longer optimal. That is assuming that you guys are running the optimal settings... Which 90% or more are not.

The reason why this is important is that in some cases changing the timing might really help you when that setting really hurts others.. So you need to develop a system to adjust, Cam, AFR, Timing and boost to find out what works. This is why it took me 4 hours of dyno tuning straight to find out what works well. When you change your VE you need to change your timing and AFR.

Side note.. The Cam wheels stop at 30 degrees. Dont bother using huge values.. They will only go to 30. The JDM V8s go to 40.
