    I have been learning and playing with my LLY over the last few months. Are you towing heavy or anything in particular? Do you have any complaints with what you have? Could up the boost some more and some more PW if you wanted more power. Not sure what all is done to your truck either.

    the truck is all stock with egr delete and an S&B intake, the truck seems fine and is getting great milage and the heaviest thing I tow is about 10 to 13 thousand pounds but not regularly, I'm more curious about injection timing over anything else.

    It seems ok. You have it kind of advanced for the injPW but it should be fine. You are asking for a lot of boost also. Duramax forums are much better, but then again there isnt many DIY tuners anymore. You also didnt "delete" the egr. You probably put in a test pipe for calibration/troubleshooting.
