We have seen 18RWHP gains on an LS1 motor just by re-flashing the ECU with a new tune. It would be reasonable to assume that you could get at least 30RWHP out of the L76 just by retuning the ECU. You would definitely see more torque because GM is notorious for Torque management and we turn that off on everyone one of our tunes…
