Hello, Lextreme! I’m going to be swapping a 3UZFE into my Mitsubishi Montero Sport and the engine I’m buying is from a 2006 Lexus LS430. When looking up the specs of this car, I’m seeing 276HP. I thought the 3UZ’s had 290/300HP. Why the difference and how can I get it back up the 300HP range? An ECU tune only adds about 10% or so. Is this the difference? Just the tune on the ECU?
