I'm still on stock tires and I wasn't using launch control. I was running Map2 since I was on a tank of 93, which is 4 pounds of boost over stock, which the JB+ also does. The power difference is much more noticeable from a roll than a dig because of the traction difference. I mainly want the tire swap to get some more grip from the dig.~ Your follow up makes me believe the JB+ was just what my ‘21 3.0 needed. An added bump in hp and torque without making the added power near useless from 0-40 mph as with the JB4.
Also, a few plusses for the JB4 is seeing more useful info about the car like boost, custom maps, and a valet mode (haven't used it yet, so I don't know how it actually behaves).
