[TimT]

If you set the cams to specified timing, changes in cam timing just moves your power band around...advance the timing and power comes in earlier, retard the timing power comes in higher at higher rpms ( I may have this backward.. I do get confused sometimes)

From the set up on the vids the looks like tuner knows what he is doing.. just wondering what iterations he is using when tuning your engine..

And one thing I notice where is the dyno? You can tune all you want in no load areas of the maps...this is the most coarse of tuning baselines..

You need to drive the car against something... ie drive it on a dyno and apply some load, make the engine work...
