More information about the calibrations:


.91/93 Octane runs 29-30 psi of boost, careful consideration and precautiosn have been taken to ensure the engine is not sustaining knock even running these boost levels. The peak power gains are incredible as can be seen in the pictures above. Green line is our 91 octane tune, VS the yellow line that is the stock calibration. Power is up EVERYWHERE in the powerband/RPM Range.


.E40 Mix, this calibration run approx 30 psi of boost, again absolutely knock free, and the extra octane allows us to add some ignition timing advance and hence wake up the car even more! This is the perfect calibration for those that want to modify their GRC even further down the line, with full bolt ons, this will net you close to 350whp! 


It is recommended to add an ethanol content gauge to be able to track your mixture, (Down to E35 and up to E45 is fine). You can also use an online calculator to determine your exact etanol level. For instance, 3 gallons of 91 Octane, and 2 gallons of E85 will give you E38 on an empty tank!


E85 is very effective and possible, simply choose E85 from the drop down menu, and no mixing is required! Once Ecutek released map switching (Mid april) You can also add a second tune (Pump gas, race gas, or any fuel of your choice) for an additional $300!
