SICKS-O did you do a buzz test with the new injectors in 7 & 8?

Yes all good.
Here is what I have done since last post.
Did the buzz test, everything sounds good on all 8 cylinders. Contribution test is good on all 8 also.
I am lost as to what is going on here.
Now the truck doesn't have the miss, but also has very low power even with the FU chip on 100 hp setting. It feels like the chip isn't even in the truck. my boost used to go to 26-28 psi now it only goes to 15 psi max, blows black smoke really bad. Even smokes on the idle, it is also black, sitting in garage for 3 to 5 minutes, when warm and idling, will burn your eyes really bad.
Oh MPG is down to average of 8.
I took the new injectors out of 7 and 8, put old ones back in, truck still has no miss, but the rest is still the same- no power, smokes on idle when warm, smokes driving it, with the FU chip in.
Take chip out and everything runs perfectly. No smoke, no miss, nothing, and has power, contribution test good, buzz test good, boost up to 26psi, 16 mpg average. I am LOST
Any ideas now? Ready to trade truck off, but can't with it running like this.
Could there be thick oil trapped in a injector boss that causes the solenoid to buzz correctly but injector not work right??????
