Your Pro 575 should have a D2 controller. Thus, you should be able to replace it with the upgraded D2 controller for the Ironwood with Super Smoke. However, it is not an inexpensive upgrade as the controller costs $330. Furthermore, I rarely see anyone that is satisfied with the added smoke flavor using Super Smoke. Thus, you might spend cash on the replacement controller and still end up using smoke tubes.
You might want to do some searching of forum posts concerning Super Smoke before deciding what to do. I have an Ironwood 885 and have never used the Super Smoke feature.
If your intention is to make smoked jerky or salmon then the Super Smoke might help. In that situation, smoke tubes might elevate the temperature higher than you desire.
