Not necessary, but there are minor AFR changes from running it. It's not completely apples to apples, but going from being tuned on the M370 to the stock, hp dropped from 304 to 300, with tq dropping from 243 down to 230. After I retuned for the stock manifold, those numbers both went up by 6 and 5 respectively.
