any start problems at 50d F?

what's the cold idle rail pressure? should be 5000>7000 psi

if both are good, nothing to worry about unless one of the new injectors has a bad partially plugged tip. been know to happen

what you running for fuel filtration?

If you just replaced everything like that and those tests pan out, then I would say its normal. You have no cat so it's not there to catch the junk/ fuel that doesn't get burned up before the engine gets warm.

My truck will belch out white/grey smoke when its cold and even a little bit the other day in 40 degrees when I hadn't driven it for a few days.

were all the FI tips equally coated in carbon?

no CAT will make more white start up exhaust. more visible steam condensation than cold diesel mist.

the pre CAT carb'd big block V8 gas engines had tailpipe condensation steam in clouds, thing of the past
