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

I have had juice on my last 2 trucks , both had issues nothing big but my new lbz truck is going to get custom software.....maybe live EFI or a JK custom tune, havent pulled the trigger yet. I have read some good post on JK custom tow / econo tune. not huge numbers but the stock trans cant deal with big power ! my feeling is 70 hp is about the most a stock trans can handle with the LBZ , the older trucks 90 hp is about the ceiling.

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 .
