I was doing some reading on here and thought of something that I cannot find an answer to. I have a 2004 SR5 V8 AWD that is supposed to have 235HP. I was reading that the 2005 V8 has 270HP. What did Toyota do different? Is it something I can do or add to my 4Runner to get that extra HP? Is it a different program in the ECU? Just curious and started thinking which usually gets me in trouble and costs me money. LOL. Thank you in advance!
