Is it possible he's wrong?
Every GM car using a current ECU will keep the engine tuning right for the conditions. My car has more power at sea level than it does at 3500 feet of elevation. When it drives into elevation the mass air meter and baro sensor are seeing the change in air consumption and adjusting fueling, this is way better than the old carb days! If I can make a mechanical change that adds some air flow the mass meter will keep the air fuel stable as it was designed to do. My race is at 3500 feet, so my car is not making 275hp, it's making 12-14% less because the airflow is reduced by the altitude. If I increase the airflow by the 12-14% the ecu will "see" the air entering the engine as it passes the mass meter, then it will deliver the fuel I need for all the 275HP. I believe the confusion might be in people thinking I'm attempting to increase the power above what the engine originally made, that could get into many over torque models made for protecting the engine-clutch-trans-rear axle. I came into this forum looking for specific 6th gen info on bolt on mechanical parts, I have a good understanding of how the engine and ECU work.
