K what about the + 50 hp injectors the truck has 200000 miles but like I said runs strong

 

Not needed, tuning can provide enough power for way less.

 

i am in to my truck right now with the same issue i pulled the heads and the headgaskets were leaking around the bottoms of the head gaskets and number 8 injector cup was leaking the rest were ok iam now putting it back togeather i hope it is all ok ill let everyone knowwith some pics of the job when i am done if it will help any one else down the road thanks for the input and the kick but site it is the best on the internet thanks everyone

 

Ya I just got mine fixed new injectors, new head gaskets, heads completely worked new everything and resurfaced. Runs well not near as much black smoke.
