help me spend 800 bucks!

Well, I have a few bucks saved up, and it's about time to waste it on my car I'll start off with a list of performance/drivetrain mods I already have, so hopefully someone can recommend something that will work well with what I got:

* Ford Racing 3.73:1 gears
* MAC 70mm throttle body
* MAC cold-air intake
* Kirban underdrive pulleys
* BBK LT ceramic-coaded headers
* BBK off-road X-pipe
* MAC cat-back exhaust
* Pro-5.0 short throw shifter
* SPEC stage 2 clutch
* Granatelli Motorsports clutch cable/quadrant
* UPR Xtreme firewall adjuster
* Ford Racing aluminum driveshaft

I have a bunch of suspension and other mods, but I'm only concerned with upgrading the performance with this 800 bucks... So here's what I've been playing around with in my mind:

* chip? maybe some sort of programmer?
* mass air sensor?
* perhaps a wms racing high-velocity CAI + MAF instead?
* plasma booster?
* bigger TB and upper intake plenum/spacer?


Please help me out, there's so many choices for this stuff out there, I'd like to find a combo that works. I can toss in a few extra dollars too if it means the difference of getting something that works well.

Thanks guys,

long term plans are a built motor and custom turbo setup.

I'm just driving the stock motor till it dies, and looking for a little more fun until then.. Its got a hair under 100k on it, so the end is coming... I already have drag radials, I only listed the performance/drivetrain mods earlier.. here's a full mod list:

* Ford Racing 3.73:1 gears
* MAC 70mm throttle body
* MAC cold-air intake
* Kirban underdrive pulleys
* BBK LT ceramic-coaded headers
* BBK off-road X-pipe
* MAC cat-back exhaust
* Pro-5.0 short throw shifter
* SPEC stage 2 clutch
* Granatelli Motorsports clutch cable/quadrant
* UPR Xtreme firewall adjuster
* Ford Racing aluminum driveshaft
* Mr. Gasket driveshaft safety loop
* Tokico struts (front)
* Tokico shocks (back)
* MAC progressive-rate springs
* HPM caster/camber plates
* Custom subframe connectors
* MAC white gauge faces
* Autometer lunar 5" tach/shift light
* Autometer lunar fuel pressure gauge
* Autometer lunar A/F ratio gauge
* Autometer tach adapter
* DMP Speedcal
* MIL eliminators
* Corbeau CR1 seats
* Schroth Rallye 4 harness belts and pads
* UPR aluminum shift knob
* UPR aluminum interior accents
* Cervini's Cobra-R front bumper
* Cervini's Cobra-R hood
* Mr. Gasket locking hood pins
* AFS 03 Cobra chrome 17x9 / Nitto 555 275/45r17 (front)
* AFS 03 Cobra chrome 17x10.5 / Nitto 555R 315/35r17 (back)


I'd really like the benefit of the advanced timing and also the upper intake plenum... which is why I was leaning towards the chip/tuner and intake plenum.. but then again i still have a stock MAF, and I heard that the MAC CAI's suck... so that drove me towards the WMS high-velocity tubes since they come with a 95mm pro-m MAF. Someone said not to waste time with the plasma booster... I thought those things had dyno runs to back them up... ????

Thanks for all the input so far,
