Introduction:  If you are like many late-model F-150 owners, you are looking for more power, torque and fuel mileage from your truck. Perhaps you have looked at or even installed a less restrictive air filter, headers or a cat-back exhaust system. These mods that help increase airflow are fairly common, relatively inexpensive and easy to install. But, there are alternatives...

One such product (pictured to the left) is the Power Module from Hypertech, Inc. The Power Module is a supplemental computer chip set that simply plugs into the service port of your truck's computer, re-tunes and optimizes stock engine settings and ultimately increases its power, torque and fuel mileage.

Rather than trying to explain exactly how the power module achieves this, read how Hypertech describes it:

"The tuning information is stored in the computer chip which controls all of the engine's characteristics like air/fuel ratio, spark advance, shift firmness, shift points, top speed, rev limit, and axle ratio. Sensors monitor many engine and transmission parameters like RPM, manifold air pressure, mass air flow, coolant temperature, intake air temperature and many more. These sensors send this information to the computer. The computer uses this information delivered from the sensors along with the information stored on the chip to deliver the optimum air/fuel ratio, spark timing, shift firmness, etc. for this set of operating conditions at that instant in time."

There is no doubt that Hypertech knows what they are doing. Many days, hours and weeks of testing go into optimizing the performance of each Power Module they produce. Their website is top-notch and one of the most informative and educational that I have ever come across in the performance aftermarket industry.

Installation:   The install was fairly simple and straightforward. The small Hypertech box the product arrived in came with all the necessary mounting hardware, a cotton swab, a piece of velcro and installation instructions. The tools needed for the installation are a Phillips screwdriver, a flathead screwdriver and a single 10mm socket wrench. The one page installation manual was very detailed, but would have been more beneficial with a few clearer pictures or diagrams.

To install the product, first unbolt the computer wiring harness from underneath the hood. (Picture 1) The harness is located on the firewall, right behind the battery. This was the toughest part of the installation for me. At 6'5", my hands are fairly large so it was difficult to get them in this tight spot. Hypertech suggests removing the battery housing for extra clearance.

Next, remove the factory computer from underneath the dash. The computer is located inside the truck just up and behind the passenger side kick-panel. (Picture 2) To reach the computer, look up inside the kick panel for a gray metal box, like in Picture 3. Remove the black clip that secures the computer to the mounting plate and carefully jiggle the computer loose, taking care not the bend the pins that connect it.

You are now ready to install the chip...using your flathead screwdriver, remove the computer's black rubber/plastic "service module" cover. Take the supplied cotton swab and carefully clean of any residue that is on the exposed circuit board. Firmly plug in the Hypertech module and secure with the screws already on the bracket.

It is now time to replace to computer to its factory location, the same way you removed it. Be sure that you have a tight and secure connection between the harness under the hood and inside the truck. Remounting the computer no longer takes advantage of that clip you removed initially. That is why Hypertech supplied the Velcro. I purchased (and recommend that you do too) a couple of extra pieces of super strong velcro to secure the computer in place. If Hypertech is listening, please fabricate a clip similar to the original to keep the computer in place.

You're done! Start your engine and follow Hypertech's instructions from there!!

Impressions:  It may be too early to tell if the Hypertech Power Module has increased my fuel economy. (keep an eye on the fuel log for that) But initial impressions are very positive. I have noticed a much smoother idle and while traveling uphill my automatic tranny is more willing to jump into the gear that I request. Based on my seat of the pants impression (I really need a chassis dyno!) I would say that horsepower has increased, though I cannot verifty their 18 hp claim. Also keep in mind that my tank was filled with 87 octane fuel when I installed the chip and (according to Hypertech) use of the Power Module requires 92 octane. We'll see how it goes...

All in all, I would say that this product appears to deliver on its claims and is well worth the money. Quality of the product is excellent. Installation was quick and simple. (with the noted exceptions) And their website delivers more information than you'll ever need to know.
