Below i listed the code and freeze frame that i got off my OBD 2 scanner. When i get this code i hit what feels like a really fast fuel cut and im only boosting 10lbs of boost. ive looked for boost leaks and couldnt find any, i got a new wastegate and blow of valve and that didnt change anything either.. does anyone kno what is going on with my car be reviewing these specs? any info would be great thanks. rudy

Did you ever resolve this problem? I know this thread is old as dirt, but I just threw this code as well and car bucked hard in third and fourth gear in mid rpm range. I need help on this one.

 

You are hitting the load values in your boost limit table.

I was fine until I swapped to an HKS SSQV. Biggest mistake by far. I am in need of the stock IX DV now. I will also replace the plugs and ensure the gapping is fine. I was fine up until the bov swap. So i am leaning toward that causing the problem.

 

well... as it turned out my car was in mitsubishi for the problem, they told me it was raining so they couldnt go fast enough to diagnose the problem.. it just so happened that i crashed me car that night, rolled it 3 times threw 3 light posts.. problem solved lol, but after i rolled it i feel as if i knew what went wrong.. either the table was off or the factory boost controller/solinoid went bad.. but yea doesnt matter to much now haha

 

Oh man, sorry to hear that.
