Or he wasn't trying.
or mayb your map is crap and u dont hav a chance against a tuned 140pd

the other thing that jbs are amazing for and probably the only way they keep customers is buy practacily locking your ecu down so if another tuner trys to acces it they can but your ecu software number and everything is changed to jbs dpf off rather than the 095647 76455 5536 that it should containe so you no wat version of ecu software u hav on ther to begin maping
