IMPORTANT NOTICE
Trilogy Motorsports Mercury Marauder Supercharger Kit
Tuning Notes
Congratulations on your purchase of the highest-quality supercharger kit available for the Mercury
Marauder.
Your kit includes a custom calibrated tune for the factory ECM that was developed by the experts at
Alternative Auto Performance. The calibration accommodates for the extra power the supercharger
provides and makes the necessary changes in air/fuel ratio and ignition timing to safely deliver
impressive power. Improvements to various transmission operations are also made to take
advantage of the increased power and torque. This calibration provides stock-like drivability and
reliability with the Trilogy Motorsports Mercury Marauder supercharger kit.
The tune must be installed using and SCT handheld tuner. The SCT tuner is not included with the
kit. If you currently own and SCT tuner for your Marauder you can ship it to us to have the
calibration flashed to your unit. If you do not own a SCT tuner you may purchase one from us and it
will be shipped preprogrammed with your kit.
The engine calibration is designed to SAFELY deliver 385 – 390 RWHP (as measured on a
DynoJet chassis dynamometer @ 591 feet above sea level) utilizing the kit’s standard 9.5 PSI boost
output and 92 octane, or better gasoline.
During the calibration’s development, additional horsepower was relatively easy to find
while on the dyno through more aggressive timing and A/F ratios. However, real-world
load and wind resistance in drag strip and high-speed testing confirmed that power above
the standard calibration put the engine into what Alternative Auto deemed an overly
aggressive tune that didn’t leave a large enough margin-for-error. A DynoJet chassis
dynamometer is an invaluable tuning aid, but cannot duplicate the exact conditions a
vehicle will encounter while on pavement.
It is extremely important to note that regional fuel quality and air density can vary greatly. For this
reason, the final engine calibration provided with the Trilogy Motorsports kit is conservative -
meaning it is safe for the variety of conditions you will encounter while driving and racing your
supercharged Marauder.
If you have any specific questions about how to safely and reliably increase the power output with
this kit, please contact Alternative Auto Performance at 586.463.0010.
