I did replace the old glow plugs with new plugs. When I purchased the injectors and turbo from Full Force Diesel, I purchased the 6 position tuner chip to accompany the package. I have not run the set up through a local diesel tuner shop for adjustments, but did not think I would need to. I'm planning on doing a point to point inspection of the glow plug circuit in my buddy's shop.
