NOTE: We are currently offering two 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: Improved throttle response, reduced turbo lag, improved low-end and midrange torque, smoothed boost curve, 15psi, producing a much more sporty feel and drivability

Stage 1: 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!
