The Predator comes with a factory performance tune that somewhat lowers the torque management but doesn't eliminate it. James at RWTD will write you a custom tune that will totally eliminate the torque management, change the speed limiter, and make any other modifications to compensate for any mods you may have done. If you purchase the Predator from him for $419, he will modify your tune for as long as you own the car. If you buy the Predator from someone else, he will give you unlimited custom tunes for $100. You can find him at diablosporttuning.com. I am very happy with my custom tune. He did an amazing job on my shifts (much better than the Predator came with), fixed my LT's which were screwed up due to my K&N CAI, raised my speed limiter to 250 MPH (as if!!!) and, overall, knocked two tenths off my quarter mile to 13.68 last Sunday. By next spring, I plan to have Nitto drag radials for sure (I just spin like a SOB) and, maybe, NOS...I'm still thinking about that (I leased my car so I want something that's easy to remove in three years when I turn it in).
