Pull the jets out, jump the board to spray and check the output/pattern. You should be pulling your jets out to clean them once and a while. I pull mine out in Spring (after Winter) and then again towards the end of Summer to clean them out.

As for your failsafes, open the WL and WH all the way to disable the failsafes and see if the problem still happens. If it was your failsafe your car would open the wastegate to dump boost and the car would die off in terms of power.
