Hi all,I am looking for something for towing heavy, but safe for engine and stock trans. What has been proven so far that has least or no issues ? Thanks

With the stock hp and torque of the LBZ, why would you want to try and mess with it and risk losing your warranty? I for one don't plan on touching mine. It works fine just the way it is. Only normal maintenance for me. Ed

Thanks, I just thought a little more would be nice,I do agree with Ed, it does pull great. And I should leave it alone. Our 07 LBZ pulls better than our 02 did w/edge set on level 2. But you know we always want more than we have.

I now have a KD custom tune installed...... It pulls as hard if not harder then my lly truck with juice set on 3 and its almost smoke free ! Runs smooth with just a slight "diesel" rattle when its makeing big power , so far its the best power adder I have had on any of my trucks. Thanks to John and the time spent developing this tune I think it will get slightly better fuel economy then stock .

Thanks Mark, Let me know how it does in the next few months. It sounds like it might be the way to go.

Well I am not sure exactly how to put this .... I have owned 5 gm giesel trucks this 2006 lbz with JK's custom performance/tow tune flat out rips ! It will tow my 31' 9000+lbs holiday rambler up hill at 65 mph at 1600 rpm and not down shift from 6th gear. This past week I went out threw the Adirondeck mountains and the Birkshire mountains at 75 mph up hills with no issues or lack of power to spare ! To be honest with you Edge juice doesnt stand a chance in keeping up with this tune , the low end TQ is truely amazing to say the least ! Empty the truck is much quicker then even the hot juice I had on the LLY truck.
I run a MBRP 4" cat back exhaust , a AFE drop in air filter and a Transgo Jr shift kit on my truck.... basicly its almost stock , there isnt many trucks or cars that can keep up to it if the turbo is spooled up. Zero black smoke , just a hint of gray smoke(almost looks like dust blowing around at the curb) . If I had it to do again to my older trucks Live EFI is the way to go but I think the key is JK has put a good amount of time getting this tune to work great ! Fuel economy on my 650 mile trip I did the math and show just over 1 MPG better then before the ECm swap ( 11.4 MPG towing at 70~75 MPH in the hills) . Highway fuel economy looks like it may be better but I only have about 200 miles empty at this time and some of that is showing the guys I can spank them big time at the traffic lights .
TX to Jk and his wife for the fast turn around , only wished I did it a mile one not at 35,000 miles ...... Fantastic tune , keep up the good work !

Thanks for the upate. I wish I hadn't asked, cause now I'll have to get one. Buy I know my wife won't let me change the exhaust. I guess it would be OK with stock exhaust?

JK say to me he is running this program in his lbz truck that is 100% stock .... NO mods , just a tune and he is very happy with the fact that is quiet . If you do just the ECM reflash and nothing else you will be really happy with it.

It certainly could, as could most any other modification.
Technically speaking any modification to exhaust/intake/tuning etc could hang you up. This is why I prefer the out of sight=out of mind approach. With my tuning, the ECM is simply swapped out and the original stashed in a safe place. No aftermarket hardware to see or fail.
