Stage Hardware Requirements

  • Stage1 - Designed for a vehicle with the following modifications:

    • headers: Stock

    • Exhaust: Stock

    • Air Filter: Stock or aftermarket drop-in filters

    • Fuel System: Stock

  • Stage2 (generally about ~20whp to 40whp more than Stage1) :

    • Headers: Stock

    • Exhaust: Aftermarket Link Pipes

    • Air Filter: Stock or aftermarket drop-in filters

    • Fuel System: Stock

Minimum Octane Requirements

  • 91 Octane - For use with 91 octane (R+M)/2 or 95RON fuels minimum. 94 octane fuels with 0% Ethanol should also run the 91 octane file.

  • 93 Octane - For use with 93 octane (R+M)/2 or 98RON fuels minimum.

  • 100 Octane - For use with 100 octane (R+M)/2 or 103RON fuels minimum.

  • E85 - For use with E85 (85% ethanol) fuel. Requires .022” gapped spark plugs

*Warning*

Using a lower octane than is designated by the calibration can promote increased engine wear and in severe cases catastrophic engine damage. Never run a map designed for high octane with low octane in the fuel tank. E.g. Do not run the 100 Octane map with 93 octane fuel in the tank.

M-Engineering always recommends new factory spark plugs gapped down to .022 when tuning your car. On higher horsepower applications or ethanol files it can become possible to blow out spark if running older plugs or incorrect gapping.

Cars running E85 MUST have .022” gapped spark plugs.

NOTES ABOUT TIRES: Factory tires and factory tire pressures normally result in high levels of traction control intervention, especially after tuning where more torque and power are commanded. As a result, this intervention can pull back throttle and power to keep the car steady and the car won’t be at it’s fullest potential. We always recommend running tires such as Toyo R888r’s, Cup2’s or any other sticky compound in conjunction with lower tire pressures.
All season tires, factory Pirelli’s, or PS4S will hold you back!

If your parts configuration or octane fall outside of the bounds of these maps we do offer ProTuning services past what is offered here in the maps. From upgraded turbos and fuel systems to nitrous, we can help!

Torque and Horsepower Output

These dyno charts represent typical power output to the wheels as tested on a Mustang dynomometer. Power gains for the Base and T are the same.

  • “Max Gain” represents the largest delta between any two points on the graph at the same RPM.

  • “Peak Gain” represents the overall delta of the highest reading per dyno plot.

  • We break up power gains into % and numerical gains. We know that every dyno reads a bit different, particularly between manufacturers, so we have utilized the percentage gains which should be similar and independent of the dyno. The numerical delta gains are a more user friendly value but may not read similar on every dyno.

 

Stage 1

  • 91 Octane (R+M)/2 or 95 RON
