Guys.....check out this video. I assume the white smoke is bad injectors? It only does it at startup if the vehicle has been sitting for awhile (8 hours or so) Beginning of summer it was just a puff. It's gotten considerably longer this last month! This video was after it sat overnight. Hope it works.....first time posting a video!
Bad Injectors??
- Thread starter GMC 08
- Start date
My LMM did the same, I didn't gain oil or lose coolant, got some fuel additive from the stealership and mixed it with a gallon of fuel and dropped my pick up line into the gallon jug and let her run til close to cavitation. I would try that remedy first...it's cheaper

Upper radiator hose is not hard. Smells like fuel. Hoping to check balance rates n my fuel pressure this week. I have the GM injector cleaner, which I haven't got around to doing yet.
Deleted n EGR blocker plate. It's been deleted for the past 70,000 miles. 155,000 on it right now.
Getting any glow plug codes?
Mine puffs and will haze for 2-10 sec depending on temp.
I just had two glow plugs go this week and mine hazes pretty good. Mine threw a check engine light for them, I know some will not depending on tuners

It was upper 50's. It does it on warm or cold days. Middle of summer 80 degrees it still does it.
So I did some data logging this wekend. I down loaded these PID files from ATPs website.
First one is Balance rates at idel.
Balance Rates Park
0-100 Run
This 0-100 run doesn't look right? The throttle position did not go to 100% Max boost seems high. Do I have the right PIDS? How do I find my Flow rate for the balance rate??

Is there a stock tune in your DSP5 tune.?

Balance rates where taken in an optimized stock tune position number 1. No sure how much ATP changes that tune?!? I'll have to give them a call
Put the stock tune back in it and see if it still smokes and as Mike is eluding to that is where you need to ck balance rates and flow rates.
Mine smells bad too. Has the last two winters, smells like raw fuel, but you can only see the haze in certain light or with headlights behind you.
Totally normal...
That's just unburnt fuel from cold cylinder walls and Pistons on start up. All deleted LMM's do it.
My truck is currently parked. I don’t drive it in the winter anymore. I’m in the process of regearing it. After that I’m completely deleting the EGR (currently just have a blocker plate). So hopefully in the next month or so I can throw the stock tune back in and recheck the balance rates.
