You won’t need to do any tuning as long as you have the speedo calibrator. As for shift points, that’s why you should do the gears, it will shift like it did when it was stock. The gears will also take a lot of strain off of the rest of the drivetrain, your truck will accelerate easier and tow better.
I wished I had done mine sooner. I can’t wait to get them broken in so I can see what it’ll do.
