h&s low boost fuel setting

[08twinturbo]

Hey guys, just did a dpf off and h&s on a 2011 6.7. Updated tuner and all is good. Running it on the hot setting and the default lbf#2 setting. It hardly even puffs when you get into the throttle. Has anyone tried setting the lbf higher and what were the results. Thanks.

Higher the lbf more smoke, more fuel and less turbo lag

Thanks. Thats not quite what I need to know. I understand the settings im just wondering if the 6.7 will improve the throttle response by adjusting it. I know my 6.4 was more responsive on 3. 5 it seemed loaded up from a stop.I guess I will try it so I can post some feedback. Thanks.

Ok, just tried it on 5. Hardly a puff from a takeoff but power is noticeable. Still has a little lag when you rev it lightly but I guess its not a 6.4. Still have to decide on the trans tuning. I think its perfect but dont know if my buddy will. It shifts much harder than the 6.4 tuning.

I have mine set on lbf 4 and I have no complaints. Good throttle response. Not too bad turbo lag.


I highly recommend the trans tuning.!

Thanks for the help guys. I winded up leaving it on 3. Thats where the the throttle response was still very good and a light puff of smoke and thats it. Felt just as good power wise on 3 as it did on 5. Very happy with the 6.7 trans tuning. It is PERFECT! my buddy couldnt believe the difference from stock. I would recommend this setup to anyone.

How do you get the trans tune?

It asks when you download the tuning if you want to tune the tranny. To change the low boost fueling do you have to redownload every time?

Yes this is correct on the trans tune and the low boost fuel. You must be on the newer udate to get the lbf options.

Also, the newer trans tuning is great. Actually the best out of any of the trucks I Have used h&s on. Firm and quick on every gear. And doesnt change, its the same every time.
