No adjustment was necessary. Spedo on 100km/h shows a 97km/h on Ways/Google Maps so seems the auto may recalibrate itself back to somewhere close to factory. Tyres are 33.2" which comes in 1.6" larger than standard.
Have also added an ARB long rage fuel (sub) tank. However the computer doesn't pick this up, extra 45 ltrs. Maybe an aftermarket hack somewhere but no big issue at this stage.
Was wondering if this is a scam. Guy selling what he says is a 2020 Prado TXL but says it has the 3.0L 1KD engine, is that possible? Everywhere I read says in 2015 the engine was changed to the 2.8L for the Diesel version. This is in Honduras.
