The Cortex (above) and the Flashpaq (left) cover the Avalanche, Silverado, Silverado XFE, Sierra, Suburban, Tahoe, Yukon, Yukon XL, H3 Alpha and H3T Alpha. These Superchips units both include multiple performance and towing tunes while working out of the box with most cold-air intakes and after-cat free-flowing exhaust systems. Superchips says the performance tune provides enhanced throttle response, optimized transmission shift points, raised rev limiter, improved shift firmness and noticeable drivability improvements. They found horsepower improvements from 14.9 to 31.2 and torque improvements from 15.4 to 33.5 lb-ft.
Both programmers will work as a diagnostic scan tool, real-time in-cabin vehicle sensor display, vehicle performance data logger for 0-60 and quarter-mile times, and speed limiter and rev limiter adjustment tool.
