Player dashes faster in build than editor

I have a script on my player that has a dash feature. The player dashes further in the build than the Unity editor. What am I doing wrong here?

     void Update()
     {
         // Change health text
         healthText.text = "Health: " + health.ToString();
 
         // Stores mouse movement data
         float movementY = Input.GetAxis("Mouse Y") * mouseSens * Time.deltaTime;
         float movementX = Input.GetAxis("Mouse X") * mouseSens * Time.deltaTime;
 
         // Restricts player looking up and down
         xRotation -= movementY;
         xRotation = Mathf.Clamp(xRotation, -90f, 90f);
 
         // Rotates player based on mouse movement
         cam.transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
         playerTransform.Rotate(Vector3.up * movementX);
 
         // Checks if player is grounded
         isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
 
         if (isGrounded && velocity.y < 0)
         {
             velocity.y = -2f;
         }
 
         // Checks for WASD movement
         float x = Input.GetAxisRaw("Horizontal");
         float z = Input.GetAxisRaw("Vertical");
 
         // Sets move direction
         Vector3 move = transform.right * x + transform.forward * z;
 
         // Moves player
         controller.Move(move * speed * Time.deltaTime);
 
         // Jump
         if (Input.GetButtonDown("Jump") && isGrounded)
         {
             velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
         }
 
         // Dash
         // Dash timer
         if (timeBtwDash <= 0 && dashAvailable == false)
         {
             dashAvailable = true;
         }
         else if (timeBtwDash > 0)
         {
             timeBtwDash -= Time.deltaTime;
         }
         if (Input.GetKey(KeyCode.LeftShift) && dashAvailable == true)
         {
             currentDashTime = 0.0f;
         }
         if (currentDashTime < maxDashTime)
         {
             moveDirection = transform.forward * dashDistance;
             currentDashTime += dashStoppingSpeed;
             dashAvailable = false;
             timeBtwDash = startTimeBtwDash;
         }
         else
         {
             moveDirection = Vector3.zero;
         }
 
         controller.Move(moveDirection * dashSpeed * Time.deltaTime);
 
         // Applies gravity to player
         velocity.y += gravity * Time.deltaTime;
         controller.Move(velocity * Time.deltaTime);
 
         if (canAttack && Input.GetMouseButtonDown(0))
         {
             RaycastHit hit;
             if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, attackRange))
             {
                 if(hit.collider.CompareTag("Melee") || hit.collider.CompareTag("Magic"))
                 {
                     Debug.Log("attack landed");
                     hit.collider.gameObject.GetComponent<Mugger>().TakeDamage(attackDamage);
                 }
             }
         }
     }
