Veg Burner,

Remember the IP timing will change only about 1/2 as much as the cam timing due to wear (elongation) of the timing chain.

This is because the IP is about 1/2 as far from the crankshaft sprocket as the cam is. So if your cam timing is 4 degrees late, your IP timing is probably 2 degrees late unless the IP was previously adjusted.
