You asked whats a PDP....it got answered. Seahorse said you don't have one on your engine. You ASSUMED ChampioN Man was telling you that you did have one on your engine and when you fund out you did not, you got upset. No one is calling you stupid other than yourself. These folks here are the best in the business and offer their help on their time. Do as much research as you can and listen to what they tell you to check.
