I've been running the twins now for a couple months. One dyno session is all I've been able to make time for. The truck made 550hp on the same pulse but noticed that rail pressure is dropping on the same pulse that it used to keep perfect rail with. May be filters getting restricted, my be cp4 not being happy. The spool up is a bit slower IMO but top end pulls harder than stock turbo once up on boost.

My son raced it at the local dirt drags and they had a sled pull so I entered it without any prep at all. Snap decision since I was there anyway. Just a local brush pull series with 20 other diesels. Most of the other trucks run the series so I thought I was just wasting my money. Ended up putting 70' on the second place truck. I really like this sled pulling stuff. https://www.youtube.com/watch?v=GIIfnre7cLY

Cool! How has it affected regen frequency and fuel economy? Or still too soon to tell?

I hate to bring up an old thread, but has anyone heard any more updates or had success with Rob's emissions tunes? I just got an LML to replace my LB7 and will be going down to Mike L. again as soon as I pick a tune.

I loved my LML tune from Rob. No smoke and plenty of power. Always passed smog.

Hope I am not too late to the party! I love this thread and hope that it is not dead. I just purchased my first Diesel after 30 plus years of driving 1500s. Trying to get up to speed on how to increase my mileage and power while maintaining my emissions...... Many thanks to all who are working on this project and sharing their experience!

As far as tuning goes, ATP was shut down by the EPA recently. So I dont think you'll see any more updates to this, at least by Rob.

Freaking tree hugging Gov crooks! They do more to mess up this world than all emissions combined! Sorry for the rant, just worked for tje Gov for 30 years....

Would be interesting to know where he ended up with all the parts he was adding for those looking for more emissions friendly horsepressure.

He sold that lml not long after his last post in this thread, pretty sure he mentioned that was last of the mods done to it. I’ll ask him again when I see him at the track or the shop.
