I have a spare EGR if you wanted to borrow it. But you could probably just disconnect the wire harness from the EGR and let it throw the code and then find out if the hesitation goes away. Have you cleaned your throttle body recently? The LS1 pulls a ton of vacuum and that pulls oil vapor through the pcv and really makes the TB dirty. You might want to pull that off and clean it and the passages and iac really good. You can do the coolant bypass while you're at it.
