Left hand slip is off the footbrake. Right hand is off the 2step @ 3200

Seems weird to me that the car didn't go at least as quick as the left hand ET with a quicker 60' (right hand). Car doesn't seem to get faster leaving off the 2 step. Could the converter be too loose up top? Car leaves really well tho and carries the tires. Should the mph be higher?

Also, what is the ideal drop in rpm between shifts?
