Replaced turbo and injectors, egr valve tested. Still blowing black smoke out the exhaust. Truck has great power.

Need some more info.

How many miles?
Are they Stock size Injectors?
Was it a stock size turbo?
Stock PCM Tune?
Any Other mods?
What year?

Black smoke is fuel that isn't fully burnt. Just shooting from the hip here I would guess bad PCM tune or plugged intake. But since lack of info could be bigger injectors and wrong PCM tune.

It has 272 thousand miles, the new turbo and injectors are ford parts, it is 03 excursion

Did you buy it used? It may have a downloaded programmer on it from the PO

Yes, I have had the truck for 6 years now. Should I do a compression test to see if there is enough corvete cylinders to operate correctly? I plan on getting it calibrated- have not had it done since I have had the truck.
