This package includes multiple starter maps, Factory, 19.5PSI, 21.5PSI, 23PSI, and 19.5/23PSI dual tune activated by the Sport button. Also included are quick adjustments that give you easy levels of control for throttle response, partial throttle boost response, and turbo ramp lag. Pick the combo of settings that’s right for your testing needs!
We are currently offering multiple research calibrations based on our 1.5T maps from the standard Civic with more to come in the future. All tunes should be run with 91+ octane for expected results.
Factory Starting Point:
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Factory boost levels
Starter 19.5 PSI:

Dyno Testing 23PSI Basemap:
Gains: 56wtq, 35-40whp midrange, 34whp peak to peak. There’s more left in the top end, but we’re staying conservative. Custom tuning can take it to the next level.
Dyno Testing 23PSI Basemap with Flex Fuel Kit (E35):
Gains: 75wtq, 60-65whp midrange, 65whp peak to peak.
