This thread is NOT FOR ARGUING about what EGR does, or if it sucks, or whether deleting it has any benefits.
This thread is only here to save people time, aggravation and money by providing links to QUALITY parts & services.
Most of the pollution crap has been off my truck for years. I finally deleted the EGR valve and EGR solenoid. Because my Blazer is TBI - I had a hard time finding a Block Off Plate that lined up with the bolt holes in the GM TBI manifold (Ya, the carb'd EGR block off plates are cheap and easy to find... but they DON'T work for TBI.)
...and I needed someone who knew wtf when programming chips.

This guy programs chips for performance & towing. He'll delete the EGR off your chip so your truck isn't throwing codes at you, or program you a custom chip for your truck.
