just turning up the fuel will also cause high EGT's. by adding the turbo you are increasing the air charge to burn the additional fuel. a turbo with mild boost will make more power and run cooler than just turning up the fuel.
Agreed. Over fueling a diesel without the properly matched air is not good. Under a large load on the engine, it should only puff black smoke and then clear out, otherwise, if it stays black, then engine is way over fueled and lacks proper air flow the match the amount of fuel being injected.
I know, but it looks cool.
