I daily drive an LB7...
But, I REALLY enjoyed the 4094 stage 2 that I put on my buddy Camerons LMM to replace the stocker that failed. I spent probably the better part of 3 days adjusting the tuning in it and loved every minute of it. Built him a pretty simple DSP2 setup with a turbine braking tune, and a "kill mode" tune. His truck is stock fuel with a lift pump and full EGR delete. He drives the truck around 500 miles round trip to work every 2 weeks (he works on the rigs) plus tows trailers around in the winter loaded with 6+ sleds and it tows awesome. I've used his truck to tow my truck on a trailer multiple times (LB7 problems) and it makes me want an LMM in a bad way... Just my $0.02
