ok so yesterday i drove from Seattle, WA down to Denver, CO. My car has the APR stage 1+ and was doing really good untill I was about an hour away from Denver and my check engine light came on. When it came on i was doing over 100 and still accelerating. So today i went and found out that the check engine light came on because the there was an under boost in the turbo.

questions:

Because it had a under boost in the turbo is that under boost for my stage 1+ or the stock level boost?

Now what do I do?? do you all think it will happen again? is there any way to help prevent this when driving the car hard?

Thanks
