Good deal.. Can't wait to get my tranny tune also, but gonna be after the new year I'm afraid.. I'm on vacation now and then when I get back I've got a fuel leak to fix on my cp3 so not sure how long it's gonna be down..

Let us know how you like it when you get it back.

Conversion complete with ppei trans tune and egr delete. Truck runs great. Really don't feel much in the transmission. My mech was told by kory, I probably wouldn't notice a difference. But it's doing it's thing. Overall I'm happy with it. But probably still gonna go back to the 6.7 cummins.

I bought the pump from xdp. They had a sale at the time for 1665. So it was a little over 2k after egr delete and trans tunning. But iam getting high egts. I have my autocal on the lowest setting. S Phinney I'm still having problems with it lugging down in 5th. I took you're advice, I use the manual shift to drop it when I climb inclines. My vanes are all over the place. One min 0 another 100 sometimes 30 and so on. I've talked to countless duramax tuners and mech and no one has a definite answer. It's like it's dumbing tons of fuel to compensate for the low boost due to the vanes. My 2012 cummins never had a issue. Deleted it and never looked back. Pulled 20k loads with it all the time with maybe a small haze of smoke and 900 egts. While running 35 tire. Hell this truck Ill be on flat ground light truck and I get those Temps. Something isn't right. And I'm at the end of my budget and rope with this truck. I know the duramax is a solid motor. But something isn't right with mine.

Kory can't figure it out? Call me again and I will discuss with you some potential things to do that will make a difference. 850 545 1404. Shane

Please post what you find. These LML's are way to finicky.....

That's surprising. The stock turbo on the LML is very responsive in my experience.

I beleive what's going on is that with the 35s and how the shift timing is going into 5th gear is what's creating this issue. If shift points and lockup where to he altered to something more suitable for his combo the issue would be lessened if not eliminated all together.
