Sure, but the dyno can get you real close right out of the gate. There's always things to try, especially when it comes to suspension.
The dyno can also help spot a potential catastrophe! I've seen some crazy things when it should have been "normal" break in and tune.
Plus if you have a flat tappet cam, the dyno is sooooo much better at getting it broke in correctly.
When you break a cam in while in the car, alot of things can go wrong causing you to stop the break in process like wiring issues, leaks, or cooling issues. If this happens, it can be devastating to the break in process causing the cam to go flat and ruining the engine costing hundreds of dollars or even a couple thousand to fix. So much better to pay the 500-600 to get it right.
