what would you define a " real tune " as?
has anyone out there tried " Pulstar performance series" spark plugs ?
anything you do to screw with the engine settings at this point is going to do more harm than good unless you trust an aftermarket chip company more than you trust toyota to make the engine run correctly and safely.
all that chip does is screw with the factory ecu settings. until you are doing some major mods the stock settings are going to be the way to go. worry about tuning it when you have something thats going to change it up a lot like a turbocharger.
