I had Joe Myers do mine. Good install, no problems. I just wish Roush would let me add the 3.73 gears and the s/c boost pulley that they offer without voiding my warranty. I can understand the pulley due to the hp increase, but the gears?

One warning about Roush, you get a great tune that you can trust, but they will not adjust their tune for mods and as far as I know it its difficult for other tuners to overide the Roush code.

The Roush boost pulley would probably be all you need though (about 440 flywheel hp), and by itself it requires no new tune, but voids the warranty. Any more horsepower and you could scatter the engine without forged internals.
