Bumping this back up a year on... I just picked up a 16 LR4 and while it's fairly responsive I would love it to have a reasonable amount of power for towing and mtns. Found this thread and it all looks pretty simple for big gains. My curiosity about this setup is more inline with how reliable it is when you actually work the engine. I'm trying to build an Overland type vehicle with the LR4 which will add weight to the car. I also plan on towing an offroad trailer for camping to these places. In the winter, maybe some snowmobiles at some point. No more than 5,000 lbs will be towed. Do you think the 3.0 engine with the Velocity AP tune and pulley will be reliable long-term? Or do you think this is mostly for daily driving fun? Thanks!
