7.3 smoke

Bmcgarvie · Apr 13, 2019

So awhile ago I started trying to figure out what's causing heavy smoke on light acceleration. If I leave and push it to 2200 rpm it smokes like crazy. And just casually cursing through town it puff a little haze. I checked compression. 365 was my lowest and 380 was the highest. The injectors are fairly new. 2 years old roughly but with only a few thousand on them. Any ideas would be appreciated.

I haven’t test it but I just installed a t4 kit and it was doing it before

Tunes are for YOUR setup? You could tell your tuner and he could modify them some. You don’t have it set in a higher power setting while just driving around?

As far as I know the tuning has been tailored to my setup. But I've always been skeptical cause since the new injectors it's always idled funny and had white smoke on startup. It never did that before. Even with the old 150k stock ad's. I'm eventually planning on having it live tuned by sdk. Also the excessive smoke and puffs of smoke started randomly.

Well I'm guessing I've found my issue why my truck has been running like crap.

Think your missing something

But what caused it?

I have no clue. Have always had a fuel pressure guage. Have always run quality fuel with high turnover. So idk. I was never truly happy with the 175/80 so kinda a blessing in disguise now I can get something different.
