I've got an 06 I put a 6.7 in with all 5.9 electronics Running a 465 with Flux II injectors. EFI Tuning by Les problem is the truck is laggy down low and black smoke all the time. Doesn't matter what setting stock or race same smoke level. The higher tunes are much faster but it never cleans up. boost builds to 40+ psi really great after 2000rpm. What is the issue? I built the same engine set up last year and it was a train from idle just bury you in the seat! This build is a dog! Pretty sure I was using a 188 220 cam in the first build but somethings off!
