Default Switching to SD tune question

So I am switching to a SD tune from MAF. I also replaced my MAP sensor to a 3 bar. As expected my car won't start with the changes made. But I am wondering if I hook the MAF back up will it start? I don't plan on driving it, I just want it to idle so I can look for leaks and check for noise and then load it up on the trailer. Think it will start or will the new MAP still prevent it from starting?

BTW, no code so I assume it is still looking for the MAF.

If you change key components like map sensor or MAF, then of course the tune will need changed to accommodate these major changes.

Plug the MAF and the stock 1 bar MAP sensor and check. After you get a base tune or get it to the tuner then put those in.
