Underdrive pulleys don't help much.. they're usually the first thing that ricers get for their cars thinking that they're going to get some magical horsepower increase from them, and they don't. To further aid the propaganda marketing that those companies use, the ricers don't SAY that they didn't get much or any gain.

On top of that, most times, the underdrive pulleys aren't tested for road use, will fail visual emissions checks (for some reason, or maybe not anymore) and aren't properly balanced, meaning they'll chew up your motor and spit it out, for a potential 1% increase in engine efficiency.

It's really not worth it. Spend the $100 on something that will actually get you somewhere.

I do believe the Apex'i SAFC is universal. The VAFC is not. It's designed to control fuel/ignition curves for Honda cars when in Vtec, also a worthless "tuning tool".

The SAFC can also be used as a ScanGauge, of sorts. Given that you're running OBD-2, you're more likely to be happy with a piggy-back system instead of standalone tuning. The problem with standalone ECU tuning is that it kills the "learn" curve of the ECU. The ECU can no longer be used in "learn" mode, as it will rewrite the tune based on core parameters, and revert to OEM specs over time. Also, if you disconnect the battery, or it goes dead, your tune is gone, b/c the ECU will lose it's "learned" information and revert back to core values.

I'm not sure about emissions laws in TX, but I know that if you're going to run a CAI, you should get a reputable one. They don't all do the same thing, regardless of what anyone tells you. A dyno sheet with a standard short ram intake and a full CAI shows the same HP increase across the board, except the CAI shows a spike at a given RPM range. That RPM range can be tuned by the manufacturer to give a spike at lower or higher RPMs.

AEM makes one of the best intakes there is, IMO (and in the opinion of several thousand street tuners, apparently). If you don't want to pay for an AEM intake, ICEMAN is the next in the line. They use a light, thermo-plastic resin that actually insulates the intake from engine bay heat soak.

K&N and other oil-soaked filters have been known to cause damage to your sensors, so probably best to stay away from them. It's already been discussed 1000's of times here and elsewhere that your air filter isn't a problem anyway, under normal driving situations.

Basically, you'll want to do anything you can to make more power with the fuel you're already using, if you're looking for more power and better mileage.

CFG83 - 215/55R16's on 16x7 wheels will fit under your car, even lowered slightly.
