I search on both models 03 and (04 05) and the specs shows that the first models of OUTL. 2.4 SOCH had 140hp. This first gen. lack of acceleration so, upper models were upgraded 20hp (160hp). However they kept the same engine and transmission.
I'm trying to find out if the upgrades were on exhaust system, intaker, ECU performance or other things that aren't part of the engine.

Some Googl'n found this.
The 4-cylinder engine, while still 2.4 liters in displacement, upgraded from Mitsubishi's 4G64 design to the newer 4G69 design, resulting in a horsepower increase from 140 to 160.
The 4G64 is the second largest variant, at 2,351 cc. Early models were 8-valve SOHC, but a later 16-valve SOHC and DOHC version was also produced. All used MPFI and had an 86.5 mm bore and 100 mm stroke. The 4G64 was later also available with gasoline direct injection. The version used in the ChryslerSebring/Stratus coupes produced 152 hp (110 kW) at 5500 rpm with 162 ft·lbf (214 N·m) of torque at 4000 rpm. The Chrysler version features fracture-split forged powder metal connecting rods. The 4G64 is an interference motor like the 4G63, however, the early 8-valve 4G64 is a non interference engine.
4G69</SPAN>
The 4G69 is a 2378 cc version built in Shiga, Japan. Bore is 87 mm and stroke is 100 mm. Output is 162 hp (119 kW) at 5750 rpm (160 in the Sportback Wagon) with 162 ft·lbf (219 N·m) of torque at 4000 rpm. It has a cast iron engine block and aluminum SOHC cylinder heads. It uses multi-point fuel injection, has 4 valves per cylinder with roller followers and features forged steel connecting rods, a one-piece cast camshaft, and a cast aluminum intake manifold. The 4G69 incorporates Mitsubishi's MIVECVariable Valve Timing technology. The 4G69 is an interference motor like the 4G63.
