Gears. This gives more mechanical advantage for that baby engine. Higher stall TC will also get you into the 3.7's power band (little higher up RPM wise). SCT 9550's are compatible with most earlier PCM's (not all). Email Hemifever tuning with the p/n to your PCM and he can verify if it will work. If it does you can get custom tuning for it. There used to be a blower kit available when the engine first came out, but it was discovered early on that the ring lands on the pistons were too high for boost and they were breaking. So the kit was discontinued. JBA has also discontinued the 3.7 headers. If you can get a spare set of stock cams, you can probably get them reground to custom specs if you are so inclined. Not a whole lot of support for the lil 3.7.
