The general rule with the 370 is once you have intake, HFCs, and CBE. The three together are enough to throw your air/fuel ratio out of whack enough such that the stock ECU can't adjust for it. You'll see some gain and will have a safe a/f ratio if you are tuned by a shop that knows what they are doing.
