Subaru performance

For a newbie like me, this book is an excellent start. I own a 2005 WRX and want to start upgrading it, and would like to do the mods myself when possible. This book doesn't show you how to do things, it's more like what you can do, what you can buy, etc. And sometimes it says what you shouldn't try to do yourself (like ECU tunning) and what is a bolt-on modification you could likely do yourself.
Of course you can find all this information on the internet for free, but it's nice to have a book with everything in one place to start with.
Anyone willing to upgrade a Subaru is likely going to spend a few thousand dollars in parts and service, so $18.21 for a book is somewhat inexpensive for an extra amount of information. I'm a newbie but I have learned so far that RESEARCH is very important for any kind of mod you want to do, so this book provides you with an extra source of information and opinion from the experienced author.

Editorial Review :: The Tri-Phase module utilizes a triad of operating parameters that enable the user to select their desired performance level. The Tri-Phase functions by intercepting sensor outputs, modifying them, and outputting them to the vehicle's onboard computer. The Tri-Phase module is also compatible with most popular performance upgrades such as aftermarket intake, exhaust, and ignition systems, low boost forced induction systems, lightened and/or underdrive pulley kits, grounding kits, and many others. The Tri-Phase enhances performance in multiple ways. First, it modifies signals being read by the ECU, causing an adjustment to the fuel curve, which is what creates the increase in horsepower and torque, as well as improves throttle response and shift speed. When the ECU sees these modified signals it provides a different set of fuel and ignition maps than it would under factory operating conditions. A second feature of the Tri-Phase is it's "High-Heat Signal Correction." In short, when the engine compartment heats up, some sensors that relay pertinent fuel curve contingent information to the ECU begin to lose accuracy due to heat absorption into the sensor. The ECU then reads these incorrect signals, and leans out, or otherwise incorrectly alters the fuel curve, which hampers performance. These errors cannot be corrected from within the computer, there must be an independent unit to correct these errors. The Tri-Phase is designed to automatically compensate for these signal errors. Additionally, our easy to follow, step-by-step instructions will allow you to get your module installed in about 20 minutes, even if you don't have any mechanical experience.
