Optimal Configuration and Recommendations

For optimal performance in most applications, the Cheetah should be installed in conjunction with the stock intake horn and stock airbox. Use of aftermarket intake horns and airboxes have been found to affect the reliability of MAF sensor readings, which will negatively impact overall turbocharger performance.  Peak performance for the Cheetah on a stock truck application will be achieved in conjunction with the factory intake horn and airbox.

Consideration should be made when incorporating additional aftermarket products that can impact MAF sensor readings or lower the overall engine rpm, these changes include: aftermarket intakes and air filters, aftermarket intake horns, throttle sensitivity boosters, or larger diameter tires.  Stock application trucks that incorporate some, or all of the aforementioned items may, under various circumstances and load conditions at very low engine rpm’s, experience compressor surging. The likelihood of this occurring is higher on 10-speed transmission models. In these circumstances, the transmission should be downshifted to avoid running the engine at low rpms and “lugging of the engine”.  

Performance Module Compatibility

When utilizing the stock air intake box and intake horn in combination with the Cheetah, a high quality performance module such as an Edge HT2 or Banks Derringer will complement the overall drivability of the Cheetah.
