I swapped a 2002 5.3 into my wifeís 06 Tahoe. The 2002 came from a Silverado it was a dbc engine the Tahoe engine was dbw.
I put the 06 intake in the 02 started it up was a little hard to start but I am getting a rich code for both banks. Have been told that there were different crank sensors between the years. My question is can I have the pcm tuned for this or do I need to convert to dbc system and pcm.
