N55 DP with JB4 questions?

[JimUlrich135]

Hello all, recently a new member and just purchsed a 11 135 with an N55 and just have a few questions..

Im in the process of purchasing a dp and jb4, already have bms intake and always run 93oct. I'm in an illinois county that doesn't require an emission test so real question is, is the cel on all the time even with autoclear "on" ?

If there's a DTC and no light I'm doing the dp, but if there's a ses light on at all times, I'm not doing that to my daily. Also, what is this idle issue ppl are having at stops? Is it all the time? Does it matter with a 6mt vs a DCT?
Ive been reading and searching on the forums and havent seen any posts that have really answered my questions.
Just a few concerns im having before spending the money, time, and effort.

Thanks.
