n54 inactive light

sorry if i posted this wrong.
my car is almost fbo minus inlets/outlets. I have a jb4 with backend mhd
When i swapped the stock intercooler to a VRSF 7.5 i got the inactive light on the dash. car runs great, never goes limp.
is the light normal? at this stage?
or do I have a problem? any help/advise would be awesome.

What’s the inactive light? Can you send a picture of dash and codes

hey, thank you for reaching out.
it was the light that looks like this (i)
I actually figured it out. it was the temp sensor i moved while doing the intercooler.
I thought I had it in an ok spot but didn't.
I didn't think that was the problem because the light didn't pop up until two days after the swap.


now i have a different problem. no bad dash lights or codes thrown. but its missing/stumbles at highway speed (60)

I chose this life.

Is it stumbling while cruising? Can you provide a log at whatever driving condition the stumbling is happening? This sounds like it started happening after your intercooler install and so you might want to confirm you don't have any boost leaks. But send a log for us to look at

car sat for a over a week.
this morning I threw a new tmap sensor in the charge pipe (n20) and cleaned
the one in the intake. drove around for over an hour and it never did the stumble thing.
