Default P0106 MAP Sensor rich LTFT advise please

2010 XK 5.0 53k miles very well maintained.
X-pipe, rear muffler delete.

Getting P0106 DTC code, I've inspected for air intake leaks
and cannot find any, I also have installed new air filters.
The MAP sensor has been tested and is functioning properly,
I've changed the PCV valves as well, no known vacuum leaks.

When I look at my fuel trim (LTFT) in SDD I appear to be running rich.

any suggestions on how to correct this?

Thanks

Clean the throttle body. It is probably covered in carbon deposits and make sure you air filters are the same brand.

Thanks for your reply, I have already changed the plastic T tubing that goes into my throttle body,
so that is not the issue. I have not however cleaned my throttle body yet,
does this involve removing the throttle body or just spraying from the front?

You COULD use that CRC GDI Intake Valve and Turbo Cleaner, spraying it into the air intake prior to the Throttle Body. There is a thread in here about it. It's mostly for cleaning carbon off intake valves, but I'm sure it'd do SOMETHING to the TB.

I'm considering removing my MAP sensor (directly mounted into throttle body) and spraying GDI cleaner into the hole,
as this gets me closest to the valves, good idea?

Just an update, SDD takes FOREVER to update LTFT values, as in multiple drive cycles and or miles.

I used a ELM device to get live data, this was way more effective.
The reason my LTFT was so far off was because I had disconnected my intake ducts in order to
clean the intake valves with CRC intake valve cleaner and SDD did not have enough time to
readjust and take new averages of the LTFT after running the engine with the intake open.

will upload my current values.

You installed new air filters. If they weren't a matched pair, that could be the cause of your problem.
