I'm going to try my luck here knowing almost nothing about engines and diesels. This actually has been quite informative, and I've learned some new info .

1) Trick question! It has two.

2) Multiple - I guess for our purposes - 4-5? Pre-injection, Main-injection, Close Post-injection, Late Post-injection.

3) From all the reading I've done...PSI means very little if the car can't handle it. Since most piggy backs are modifying and plugging into MAF, MAP, and TMAP sensors, my money is on MAF (mass air flow) sensor. This is the amount of air the engine is taking in. More air...more compression...more hp?

Please feel free to correct me so we can learn more. This is great info.
Isn't it Twin Power Turbo? I will say one turbo with variable turbine.
No clue about the injection, I know it passes the piezo but not sure what happens after that.
The more cool air you can jam into the cylinder the more torque? PSI?

I was never any good at trivia
But I am learning a ton here.
