is saying because you have the JWT ECU you think you cant delete the EGR? If that is the case the JWT ECU wont matter and you can delete the EGR completely with ease and save you a headache when pulling the plenum. I did the TB Water bypass and EGR delete and AIV and it made my plenum pull a snap only taking me 15minutes. I would suggest it big time but retype your begining sentence if im wrong.
