I owned 99 Lincoln Town Car, with the 4.6l. It would blow the doors off my 2000 4.6l Expedition. It was hard to believe it was the same motor. I suspect Lincolns are tuned different.
There is company called Jet Performance Chips. They sell a pricey $250 add on, for the PCM. It installs in between harness and PCM. They claim all around better air/fuel ratio, spark timing, power and fuel mileage.Yea it all depends on the application. The 4.6L in half ton application is built for dependability and torque vs being tuned for higher rev and horsepower in a car. Less output generally equals more durability from the engine. Same thing comparing Raptor 6.2L to Super Duty 6.2L.
Apples and oranges! Weight for sure, final drive ratios, transmissions, drive trains, etc. also most truck engine derivatives are tuned for lower RPM torque. the 4.6L had several different iterations. a lot of them had visible differences on the top end via different intake manifolds. the manifolds had different length runners and other differences for torque vs power etc.I owned 99 Lincoln Town Car, with the 4.6l.

Likely different turbos, head and tuning.
