Ive read under high acceleration the egr solenoid opens and just releases all of the gases to make more power and can make a smell but idk if its true. Ive never had a car smell after ONLY harder acceleration or driving high revs. Only my dam Z I hope its nothing serious
Exhaust Gas Recirculation (EGR) would be around idle. On some cars the intake valves are open just enough on the exhaust stroke to let some exhaust gas back into the intake runner. The exhaust gases cool then find their way back into the combustion chamber on the intake stroke. Exhaust gas helps lower combustion temperatures which reduces NOx.

To use a diesel for example if the EGR valve is stuck open while trying to accelerate there will be a lack of power and black smoke out of the exhaust. This is because the boost is going through the EGR valve, through the EGR cooler and out through the exhaust manifold.

Where ever you read that exhaust gases increase performance makes me laugh.
