Do you have a transmission cooler? Not related to your post but might consider one. I live in hot South Florida and fastparts adjusted mine with their tune. After driving never had them stay on. Mine stays below 210.
That’s the same unit I have....it has a few settings....I have mine set so that it does not pulsate every time I hit the brakes during heavy traffic. There is an interval setting so it does not become annoying.
There is a thread with “Who built your engine” which you might find useful. Reach out to GT Joey or the GT guys they should have more info if no one chimes in.
