I have a 2006 Trailblazer with a 5.3 that I have Deleted DOD on, bored out to a 5.7 and installed a towing camshaft into 200/209 502/502 113. Other than that it remains largely as the 5.3 was. I was wondering other than turning off the DOD what other changes to the programming might be recommended for safety sake before firing it up for the first time?
Thanks
Roy
