I just replaced the injectors with Stanadyne G codes that were pop tested, rebuilt IP, new o-rings, caps and return line. Clean Air filter, fuel filter has less than 1,000 miles on it. The truck has been timed and is at 10 degrees. I can only get maybe 3 lbs of boost if I nail it in top gear. Lots of black smoke for a bit and it clears. The truck has a ATS turbo upgrade with the intercooler. I modified the boost controller and when I had boost, it would hit 11 lbs no problem. What should I do first?
