P204F Code Help

Just turned 18,000 miles engine light on dash. Plugged in OBD2 with Torque Pro and have Powertrain P204F code.
Explanation says Fuel & Air Metering & Aux Emission Controls.
I have GDE Hot Tune with K&N Oiled drop in Air filter. Any help or what to look for? I cleared the code and drove the vehicle 10 miles without any light back on. Thanks.

I believe an RRT was put out for this code: http://www.wk2jeeps.com/tsb/tsb_wk2_1802315.pdf

I think there's a new 02 sensor as part of the update as well.

Looks like according to the service bulletin it's a software only fix.

Re: P204F Code Help

Have you contacted GDE?
This may be first mention of MIL with Hot Tune
Not sure if this is accurate

If dealer applied RRT this would overwrite the Hot Tune, then GDE would have to rescan with their latest version

I sent them an email at support address. Waiting for a response. I drove another 25 miles after I cleared the code and no return of MIL.
