CJV, Does the ECU need to be tuned to get the reduced lag or just the coated headers will do?

When you retain heat, the result is a leaner combustion. To take advantage of the leaner combustion you need to add fuel. This is how the power is increased.

So to answer your question, if you make the headers more efficient you need to tune the ECU.
