I'm wondering if anyone knows of a good performance chip for the Lincoln LS? I'm prepping for an extensive exhaust project. I'm gonna custom build it from the cylinder head to the tail pipes. My prediction is I will yield 10 to 50 HP and a luxury sedan that sounds like a formula 1 car. I want to chip it to really get some power to go with the sound. I'm not an idiot, all stock sensors will be used and I know how sensitive newer engines are with exhaust back pressure. So please only post suggested performance chips.
