The Me-109 has better performance in higher altitude compared to FW-190 with radial engines (series A). Thus the 109 was kept in production, and even upgraded with DB-605, a more powerful engine with better supercharger, making the plane comparable to late-war adversaries.
Moreover FW-190 has a problem with heat. Although a radial engine, it needs an extra reciprocating fan to be installed in front of the massive BMW 801R to cool it down. Installing a bigger supercharger will only increase its weight and reduce reliability. Thus it can't fly high to intercept Allied bomber formations, let alone its escorts. But then FW-190 got new engine, it was called FW-190D, the long nose Dora, which is fitted with Jumo inverted V-12 engine. It became perfect. The Jumo (forgot the serial) can produce up to 2,000 HP at boost, enabling it to match the latest American fighter. However, its aging airframe design from 1941 limits its top speed. It can't easily catch or outdive Mustangs nor Thunderbolts.
