Cutting out in boost?

I have a boosted b18b tuned on 12psi on EcTune by a local guy around my area, I've had the tune for almost a year now.

About a month ago, it would intermittently have a slight hesitation every once in awhile in boost, it would happen at random times. Now about a week ago, it started doing it alll the time. It will cut out around 4k rpms in full boost and feels like its hitting rev limiter almost. My afr's are dead on. Ive already replaced all ignition components, coolent temp sensor, map sensor, checked timing. Im out of ideas.

Could my tune have went bad?

Anyone have any more ideas on what could be wrong?

thanks

Do you guys think the solder points on my chip need to be touched up? i just opened up my ecu and a couple of the points look like they have harline cracks

If your chip had some sort of lean protection it might not be calibrated to your 02 sensor correctly, thinking you are lean and cutting spark.

What are your AFR's in boost? Could potentially be a bad tank of gas, I just find it odd that 1. The tune would go bad after a year of it running good and 2. The chip going bad after a year of it being good
