I have a Smarty S06 POD programmer with REVO for my truck. It has tunes in it ranging from half stock power to +170whp over stock plus ability to run 1-100% of any tunes power. It also has the ability to adjust timing, fuel rail pressure, torque management, wastegate on/off, tire size adjustment, and 25-250mph adjustable speed limiter. Should lowering the power output causing it to be under more load be more fuel efficient? Testing now running +30whp tune and 25% power output. So far have noticed higher load on motor, no smoke, slower boost climb, and less overall boost. Will see how this helps/hurts mpg but curious on what in theory it should do.
