It is *really* fine. I will not retune.
Edit: I actually did. Worked with one of the most popular places. They sent me a tune which was garbage that I couldn't even drive. Second iteration was no better. I said keep the money and cut the chase, installed the stock MAP sensor and flashed back the JR factory tune which is working great.
