Ahh, but it sounds like the entire kit will carry a full warranty & piecemeal will probably not. For those of you who have already kiissed-off the warranty, that may not matter. For those of us who want a warranty, waiting for the kit might be the preferred course of action.
From where did the 312 - 315 HP/torque numbers come? And, do we know if that's at the flywheel or rear wheels? Even if those #s are at the flywheel, that may be enough of an increase for me; especially if it carries the full warranty.
