I understand that in gas vehicles you add more fuel and nitrous at the same time and retard timing and other tuning issues. On a diesel you add n2o and it cools egts at the same time plus make hp. Is it possible to have a lean condition and burn a piston or hurt ring glands? If your way over fueled how can you hurt a diesel motor if its already 1500* + on egts by adding n2o. Plus tuning issues. Not like you can pull a sparkplug and check it? Just go by egt gage?
