I bought my sc 3815 right after I bought my trk in 06 (it might have been 07 when I chipped it to perf 91 oct!) I have been running the same setting since!...(if it aint broke , don't fix it right), My trk is running great!..My q? to the hemi God's is, Is it time to upgrade to a new setting?? signed: an old timer who dosent like change but wants what is best for a long lasting beast, My hemi!!!!!

I am with you and if you are satisfied with what it is doing now then i would leave it but i am sure since then they have done some improvements to the programing but i dont know for sure i am sure one of the real gods will be around shortly to help you with this
