I've got an APR tune on my GTI, so I've familiar with ECU mapping. Increasing power output is one thing, but how can your tune reduce emissions while keeping all the OE emission equipment intact? Seems like that in and of itself would be something Jeep and the EPA would want, as well?
Also, I had a 2009 BMW 335d whose DME (ECU) could adapt to slightly higher cetane levels if you could find the better diesel, like what is available in Europe. Given that in Texas metro areas we enjoy State mandated minimum levels of 48 cetane, when I added a little Amosil Cetane boost it was like the engine was running on glass - just as smooth and powerful as could be. I'm curious how the GDE tune handles various cetane levels?
