The loss of power probably has more to do with IAT than coolant temp. The ECM starts pulling ignition timing, &c, at around 90F IAT. IAT is usually a few

My _guess_ is that the changes made to reduce power are causing the change in exhaust sound level. Maybe the exhaust valves are opening sooner/longer to reduce effective compression.
