To start, my car is basically stock with mods in sig.

Work gave me a $100 Amazon gift card and I'm trying to find the best way to use it. I am willing to spend about $200 total using $100 off the card.

Not listed are my gauges. I have the autometer center lower gauge pod and 3 cheap JDM guages.

JDM Boost/Vac - hooked up working.
JDM AFR gauge that had the green wire cut (previous owners wideband or narrowband hookup, not sure which the gauge is).
JDM Vac gauge which is pointless and disconnected.

I am currently looking for these items.....

Wideband compatible with ECU controlled boost, and logging.
Parts for ECU controlled boost since I'm heading that direction.
Boost and AFR gauge that can show peaks so I don't have to stare at them while accelerating.
Column dual gauge pod for AFR/Boost gauge.
Tactrix cable (unable to find one on amazon or else it's my #1 choice since I don't have one yet)
Underhood Shifter bushings.
Replacement for my left HID bulb that takes multiple attempts to light up.

Basically trying to find the best way to apply that $100 ($200 total) and get the most done with the car. Any suggestions are welcome too. This is my DD and will see mostly street duty and some snow. Keeping it reliable is my goal.
