Paint your steering linkage, diff covers, knuckles, and wiper arms neon green. You will net 36.2 horsepower with the simple use of a rattle can.

Improving the power to weight ratio is just as effective as adding horsepower. Pink paint weighs far less than any other color of paint and that is a fact*.

On a more serious note...
Cat back exhaust (unless you feel the need to do a high flow cat). If on a budget, you can get away with a glasspack (I'd keep stock diameter exhaust). Duals versus single, there isn't any flow difference, it's just the look and a slightly different sound. Tips make the biggest sound difference. Bigger tip, louder and more annoying the exhaust.
Upgrade the injectors (optimized injector tips, optimized spray, optimized burn).
If you have the time, either A) bore the throttle body or B) acquire a pre-bored throttle body.
Some form of air intake that flows better than the factory one (K&N, Air Raid, aFe). Safari snorkels do not offer better flow (still using the factory airbox and intake) but depending on the factory intake location they may have a somewhat ram air effect at speed.
Most of the tuning options out there are built for mostly stock engines (mostly just messing with shift points in the transmission), when you start doing some old school hot rodding techniques (injectors, throttle bodies, intakes) your really not doing much unless your going with custom tuning. You won't see a huge benefit from a tuner, you'll see increased throttle response with the intake and throttle body and for most stuff like that, the engine will self adjust to adapt without retuning it.
