Just needs a board or some pipe redirection.

Hot dang we got ourselves a sloppy Gale Banks here boys. This is why diesel tuners say a good tune shouldn’t smoke a lot

Firepunk diesel did a great video taking about their drag truck and the fuel ratios, it's effects on egts and power. On and off nitrous.

From the look of it you had a more efficient burn on the 35/1.

I'm not sure the load you can do on your dyno but that makes a huge difference for diesels. It's more important for the higher hp trucks, but it's why you see guys with the rear parking brake on when on the dyno. They release it at some point in the run. This is on a dyno that can't provide the load the truck wants to see.

Looks like i need to bring my lb7 by, that 400 horse tune is cleaner than whatever tow tune is in mine😂

And I know you’re the master when it comes to hp tuners so I’m wonder if I should buy the new hp tuners like v3 or older one I’m also gonna be helping friends tune there new and older cars/trucks thanks 🙏 I appreciate any information you give

Curious what happens when you have too much fuel down low, does it still make more power? trying to figure out why so many tunes just dump in so much fuel down low before its ontop of boost.

LB7 is the only duramax with the wastegate on the turbo. The rest use VGT. Might be gummed up or have diaphragm issues if you are seeing different power for the same runs

Got a lift pump added to it? If not, maybe it's sucking a feed line closed randomly.

Log trans slip? Sure the ECU was actually giving you the requested pulse width and timing? How much did you increase boost? Yes, you can overfuel and make less hp sometimes. Seems to me like there is a different issue here though. Diesels are way fun to tune! So easy compared to gas stuff.
