Installed AEM water methanol kit, then went for dyno tuning at LSF Sunway with Matt Dirin and Akong. Got 376whp/410wnm @1.4 bars on the Mustang (est. 470hp/530nm on crank). Methanol fluid ratio is only about 33%. Not too aggressive tuning but pretty pleased coz target exceeded so stop power mod for now. Maybe would only consider Link ECU if got a good deal somewhere.
Downsize rims to 17x9 Konig Hypergram, lighter by 2kg/corner, plus got some AD08R. Previous 18' got buyer already.
Next plan just do corner weighing and change android head unit.
