Hey guys Im looking at buying a used T770 highflow to use Mulching. The unit im looking at is a 2014 or 2015 model with the t4i kubota motor in it (pre complete tier 4) with only 200 hours. I found a company that offers a ecm reflash for this model that increases the horsepower and overrides all the emissions sensors on the computer. My question is has anybody deleted the dpf, Regen system, and egr on one of these yet?
