We did some distance testing and have some results on the ATP 2013 LML; This truck is a 3500 CCSB with 400 miles on it before this test so not broken in. The weight of the truck was 7650lbs when driven across the scales at a highway weigh station with ¾ tank of fuel. Totally stock with nothing added or taken off from the way the factory built it.
Stock tune averaged 17.95 mpg and averaged 11.3 miles per gram of soot accumulated, no regen during this time (250 mile run).
Street tune averaged 18.28 and had a regen during this test. Averaged 22.7 miles per soot gram (230 mile run)
Dyno/high performance tune averaged 19.38 mpg and averaged an amazing 112.75 miles per soot gram, no regen during this time (500 mile run).
Speedo limiter is tested and confirmed to be removable and cruise still works fine.
So an 8% average in fuel economy but a great reduction in soot at a minimum. This should increase fuel savings over a longer test as the truck will not regen as frequently. I’m not sure about DEF costs as the truck doesn’t seem to be using any. More testing will be done to see how the street tune does without a regen and to confirm the crazy soot reduction on the high performance tune.
So testing is going well. There are many tests still to be run but things are looking great. Overall this thing rips right now with the high performance tune. It has a pretty rapid climb in soot production when bombing around town beating on it so I have some work to do there. Around town MPG has been in the 15.5-16 range testing different tunes and a very heavy peddle including burn outs and power braking and spool up tests.
We don't have a time frame on the release as we are still working on parameters and testing.
