Need Help Finding a Starting Point

slower pass with 10lbs
Faster pass with 9 lbs. Both pressures felt like the car was spinning. Just wanted to make sure I didn't lower the air to low.
Wheelie bars at 2.25 and on them fast.
Ladder bars set neutral
Spotter said tires up about 9 to 12 inches

Kind of weird when you run an eighth then coast the rest in third to a 12.0 at 55 mph.
