Need more cheap upgrades

[SwtNLwPT]

I have been doing the cheap stuff first. I have not really done anything big and money is very tight. I have as of now...

Mopar BOV
AMX Up pipe
K&N Drop in
Air box silincer removed
Eibach Springs

This is the small cheap upgrades so far. Where should I go? I do want to get the Stage 1, but I am not ready yet money wise yet.

It's an '03 Turbo with 18,000 miles on it. I been thinking about a ignition coil, plugs, and wires. Is this going to make a difference? What brand should I go with? Should I also change the fuel rail or wait for the stage 1 to do that? Should I change the WGA or wait on that as well? A little help. Thaks

Get a cheap intake and a boost controller. Intake does a heck of a difference and you can pick up a manual boost controller for like 20 bucks. Just stay conservative...

In fact in a week or so you could probably pick up my old Airraid on ebay for cheap...
