How to squeeze extra 57HP out of 3.8L Pajero! [Dyno Testing]

This video explains my modification journey with the Gen 4 Mitsubishi Pajero 3.8L engine. I have owned this car since 2008 and have documented the performance part upgrade journey and dyno tests throughout the period. After the upgrades the engine is now technically 3.9L. I am also not affiliated with any of the brand mentioned in the video, its all done through trial and error. Below is a list of parts featured in the video:

Phase 1 Parts:

1. DR15SXC-WC Evo Laser Spark Plugs
2. MagnaFlow 59905 2.25in High Flow Catalytic Converter
3. Fox 3 Inch Muffler with cut out
4. Ebay Australian Headers
5. AEM 21-2019BF DryFlow Air Filter

Phase 2 Parts: Piston Upgrade
(Mitsubishi Part Numbers)

2. +0.5 Piston Ring: 1110A499
