The K&N cold-air system for...  The K&N cold-air system for '05-'10 Mustangs is another kit that requires a little construction quickly taken care of with handtools. Of all the no-tune CAIs we installed, the Three-Valve unit seemed to create the leanest air/fuel ratio. Having tested this piece in a previous effort, we know that it definitely shines independently when it's installed with a tune.  BBK Performance provides 7...  BBK Performance provides 7 mm of additional throttle-body diameter with its twin-bore replacement for the stock 55mm piece (top).  Three-Valve throttle-body...  Three-Valve throttle-body swapping requires installing the OEM throttle-activation motor and TPS on the BBK piece. As a drive-by-wire unit, throttle-position voltage must be verified before removing the stocker (Tony's is 1.20), and then duplicated (within 1.19-1.31) when the upgrade is in place. The PCM will kick into Fail Safe mode if TPS voltage falls outside the recommended parameters.  Three-Valve throttle-body...

Here is a look at the Three-Valve 4.6 DynoMax 3-inch after-cat system with its 4-inch stainless-steel-tipped Ultra Flo Bullet mufflers (right) and the heavier, restrictive factory tail pipes. Notice how dramatically different the curvature is between the two systems? The factory setup has far too many bends--especially in the over-the-axle tubing. Gases actually travel backward slightly (toward the front of the car) before being channeled toward to the mufflers.  Obviously, the catalytic converters...  Obviously, the catalytic converters are the biggest downfall of the stock H-pipe, as is its 2-1/2-inch diameter. Nixing the cats and increasing the tube size with BBK's X-shaped, 3-inch crossover brings a lot out of an S197's Three-Valve engine, especially on the torque side.  Final fitting of the X-shaped...  Final fitting of the X-shaped crossover tubing and exhaust pipes is an exercise in rotating, pushing, and pulling in order to find the correct positioning for the exhaust tips.  Ricardo loads Chris Jones's...  Ricardo loads Chris Jones's all-bolt-ons PCM calibration using SCT's SF3 flash device. Blow-By sets up similarly configured Three-Valves with 30 degrees of (total) timing.  While this map was effective,...  While this map was effective, it still rendered air/fuel a little too much on the lean side for our liking. To optimize air/fuel, Ricardo richens fuel by 8 percent.
