Default Re-Dynotune After Underdrive Pulley?

Going with an underdrive pulley and would it be helpful to re-tune the car with the pulley? ...I mean I know it will help but is it cost wise worth it? Or could it mess up my current tune if I didn't re-tune it? How much rwhp would I get either way?

No retune should be necessary...you aren't changing the airflow into or out of the engine.

Somewhere between 5-10 would be my guess...

yeah I would say not to worry about doing a retune at this point.

Reducing friction or rotational inertia won't require any tuning. Those mods are less than the difference of having a passenger in the car.
