I've been trying to search the forum with no luck to see if anyone else had this issue.

I recently installed a dawes valve kit, erg blank and 3" exhaust. When driving at highway speeds with a steady pedal the Patrol would go into a "temp" limp mode. After coming off the pedal for a sec and back on it would go just fine. Through investigating I noted the boost would come up to quickly for the Dawes kit compensate but it would still occur. It was only after removing the blanking plate would the valve kit work correctly.

The blanking plate that I purchased did not have the hole as I had seen in others, but based on the position the instructions indicated for it install it didn't cause the dummy light to come on, so thought all is good.

Any ideas as to what is causing this? I currently to not have blanking plate in and would like to put it back. Should I put a hole in it to allow some recirculation?
