How to make a stage 1 tune:
Open stock calibration map in WinOLS
Increase torque
increase torque commanded/targets
Increase VE (Volumetric Efficiency) targets in multiple tables
Increase exhaust temperature limiter
lambda
increase or decrease lambda targets when tuning for more power?
more pressure = more fuel = more power, right?
more timing = more power, right?
what might these be?
