hey so i pulled this code yesterday, after my engine service light came on. it happened when i did a 1st-4th pull, shifting near redline at every gear. when i hit 4th, the light came on and my car went into limp mode.

ive had previous problems with my car overboosting(which my mbc solved) and with a failed maf sensor, which led to limp mode as well. but it was a differnt limp mode where it would force my rpms down to 2k.

the limp mode im in now does not force my rpms down to 2k. however when i idle, it only idles at 2k.

anyone had this code before??????? p0109

 

I think there is a list of all the codes and what they mean if you do a search.

 

This should go away after you turn the car off and flickr back and forth the key in the ignition before then turning the car back on. Stay out of high boost...Till issue is solved.

Were you previously tuned before?

I ask because I had a Cobb AP stage 2, I then unmarried the AP and have a MBC that was near 30 psi and I had limp mode kick in twice.
I turned the boost down and eventually had a friend tune my car again and now no issues.
