So I bought a 2011 Suburban a while ago, and I never really touch it outside of typical maintenance. The carfax shows an accident, and I recently had check engine light come on. I pulled the DTCs and decided to pull the tune, and I have only ever done Gen 3 LS. The E38 has a lot more to it than a P01 obviously, but what is strange is under Tune Details the Overview shows the correct vehicle, but under controllers it shows in the third box down 2011-12 CTS-V, and under Engine, there is a tab for a supercharger. Is this normal? Also the PCM cover was missing when I bought it.
Don't recall there being a cover, just a bracket on my 2011, 2010 Sierras, or on my wife's 2011 Escalade. 11 year old truck with 1+ PO's missing parts- normal.
I figured it out. Nevermind.
