OE Tuning for GL550

Hello all, I am interested in a tune for my NA GL 550 and was wondering if it was even worth the $500ish for the tune and handheld that allows for the tune. Thanks for your comments.

They are claiming 20 - 30 hp to the wheels and 20 - 25 torque.

That's pretty much worthless on a vehicle with the weight of the GL.
