MPU6050 OFFSET

Hi i am facing a huge problem with the calibration of the MPU6050
i am coding from the beginning a code to get the raw data from the MPU6050 then adjust those values to apply on them a complementary filter.
So in order to calibrate the MPU 6050 i used another sketch that gives me the offset of my different values but when i use the line “mpu.setXAccelOffset(-16384) ;” in mine to correct those values it works just fine for all of them except the acceleration on the X axis no matter what value i give as an offset it shows me everytime the same thing here is an example of what i get :
AcX = -16868 | AcY = -20 | AcZ = 16388 | Tmp = 21.89 | GyX = 11 | GyY = 12 | GyZ = -17
AcX = -16904 | AcY = -28 | AcZ = 16352 | Tmp = 22.04 | GyX = -8 | GyY = -14 | GyZ = -10

the AcX goes from 0 to -32XXX
and here is my sketch :
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////
#include<Wire.h>
#include “MPU6050.h”
#include “I2Cdev.h”

const int MPU_addr=0x68; // I2C address of the MPU-6050
int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;
MPU6050 mpu ;
void setup(){
Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B); // PWR_MGMT_1 register
Wire.write(0); // set to zero (wakes up the MPU-6050)
Wire.endTransmission(true);
Serial.begin(9600);
mpu.setXAccelOffset(-16384) ;
mpu.setYAccelOffset(-137) ;
mpu.setZAccelOffset(1333) ;

mpu.setXAccelOffset(88) ;
mpu.setXAccelOffset(-37) ;
mpu.setXAccelOffset(2) ;
}
void loop(){

Wire.beginTransmission(MPU_addr);
Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H)
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr,14,true); // request a total of 14 registers
AcX=Wire.read()<<8|Wire.read(); // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)
AcY=Wire.read()<<8|Wire.read(); // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
AcZ=Wire.read()<<8|Wire.read(); // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)
Tmp=Wire.read()<<8|Wire.read(); // 0x41 (TEMP_OUT_H) & 0x42 (TEMP_OUT_L)
GyX=Wire.read()<<8|Wire.read(); // 0x43 (GYRO_XOUT_H) & 0x44 (GYRO_XOUT_L)
GyY=Wire.read()<<8|Wire.read(); // 0x45 (GYRO_YOUT_H) & 0x46 (GYRO_YOUT_L)
GyZ=Wire.read()<<8|Wire.read(); // 0x47 (GYRO_ZOUT_H) & 0x48 (GYRO_ZOUT_L)
/AcX = AcX / 16384 ;
AcY = AcY / 16384 ;
AcZ = AcZ / 16384 ;
