Hi All! I recently purchased a 2011 Range Rover SC and while I love all of the power it has, I would like to get a good amount more performance out of the engine. I have found very little online through research, other than a few ECU and pulley mods. Can you experienced Rover guys chime in and please tell me what you would recommend I do? ECU? Pully? Exhaust? And who should I order these products from? I'm really hoping to learn from you folks without having to waste a lot of money and/or damage the truck in the process. Any help would be greatly appreciated.
