Improved response
A correctly prepared calibration can improve throttle response and make power delivery feel more immediate and controlled.
Johnson J40 chiptuning and software optimization
The Johnson J40 catalog currently includes 1 supported generation. Select the production generation that matches the vehicle before choosing the exact engine and reviewing the available tuning data.
Different Johnson J40 generations can use different engines, control units and factory software even when the model name remains unchanged. Selecting the correct generation reduces ambiguity and allows ABG Performance to evaluate the proper Stage 1 or Stage 2 solution for a local workshop appointment or an online partner file request.
