End User Adjustability Is Now Available!
This package includes three started maps, 16.5PSI, 18PSI, and 21PSI. Also included are quick adjustments that give you easy levels of control for throttle response, partial throttle boost response, and turbo spool. Pick the combo of settings that’s right for your testing needs!

We are currently offering three research calibrations with more to come in the future. Both can be ran with 87 octane fuel, but running 91+ will give the best results.
Stage 0 (CVT):
Improved throttle response

Improved low-end and midrange torque
Smoothed boost curve, 15psi
Producing a much more sporty feel and drivability

Stage 1 (CVT and MT):
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Reduced turbo lag
Improved low-end and midrange torque
Boost raised to 18psi
Producing a much more sporty feel, drivability, and additional top end power!

Stage 2 (CVT and MT):
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Reduced turbo lag with aggressive spool up
Improved low-end and midrange torque
Boost raised to 21psi
Producing a much more sporty feel, drivability, and additional top end power!

Notes: Due to testing with a CVT the numbers are skewed since RPM did not match up on the top end. Tested in the brazilian market where the Civic X is detuned from the factory, so factory numbers are lower. These test results are to give an indication of real gains with our platform.
