Please have patience. Very few questions are answered on this forum within the first 13 minutes of posting.

Try adjusting the throttle stop set screw to prop it open a little more. That would at least be a decent quick fix.

your base map is not setup correctly. you may have to tow your vehicle to the tuner.
