Horse Sense:
Another tuning tip from SCT: Beware of race-style blower bypass valves immediately downstream of a mass air meter. The big blast of air belching through the bypass can apparently cause reversion in the meter, screwing up its accuracy.

In the past, the raging flood of aftermarket Mustang speed goodies sometimes drowned out our ability to tune the resultant combinations, with the consequence often being less-than-optimal driveability, or in worst-case scenarios, premature short-block self-destruction. It used to be that tuners faced with unusual combinations or anything at all north of, say, 450 rear-wheel horsepower often turned to such drastic steps as tossing out the street-friendly mass air meter and starting all over with some form of aftermarket speed-density system. Or, they settled for creating a relatively safe wide-open-throttle tune, while sacrificing some aspects of driveability and efficiency that are so important on a street-driven vehicle. We're happy to report those days may soon be over, thanks to the rapidly advancing science of electronic tuning. A relatively new firm, Superchips Custom Tuning, is one of the generals leading the charge in this technological revolution.

Obviously, electronic tuning is nothing new-it has been evolving ever since Ford first slapped an EEC processor onboard to precisely oversee fuel and timing strategies in response to ever-changing driving conditions. But lately we're seeing quantum advances in the areas of tuning software and hardware sophistication, user-friendliness, and the resulting ability to civilize even the wildest of powertrain combinations.

This is a good thing, because even outrageous power gets old fairly quickly without good start, idle, and part-throttle manners.

The name "Superchips" should be familiar to most readers, as the company is best known for its respected line of off-the-shelf performance chips for stock or near-stock applications. But let's be perfectly clear that Superchips Custom Tuning is a wholly separate corporate enterprise that is only 25 percent owned by Superchips. As its name suggests, SCT's specialty is on the custom tuning side, working through an ever-expanding network of dealer/tuners, such as Paul's High Performance, where we researched this article. To be more specific, SCT's goal is to engineer and put the necessary hardware and software in the hands of skilled tuners so those experts can quickly and efficiently sort out the hairiest of combinations for maximum performance, driveability, and durability.
