Banks dropped delete tuning some time ago. Bully Dog also dropped off some time ago after they got taken to the wood shed by the EPA. No one is that can be depended on is going to further crack ECM codes to do this sort of thing. The EPA is on a mission with its National Compliance Initiative 2020. It has been reported that the EPA has even gotten its hand on invoices of customers that have purchased delete kits and tuning. Now, I don't think that means the EPA will start busting down doors, but it could affect being able to renew licenses on vehicles unless they can be shown to be in compliance. We will just have to watch and see how that plays out.
But deletes are no longer a viable option, that is, unless one want to trust thousands of dollars of investment to Charlie's Shade Tree Tuning run out of his garage. That is a choice.
Nothing but the truth here. These large scale tuners are now investing in epa certification testing facilities so that emissions compliant tunes can still be sold for enthusiasts.
The good news is that diesel emissions have come a long way as far as reliability and impact to performance, just like they did on gasoline engines through the 80s and 90s. DEF alone is a game changer as far as I'm concerned.
The scale is considerably different. All the gas folks really have had to deal with was EGR, Catalytic Converters, and O2 sensors. The level of diesel emissions complexity makes the gasser side seem child's play. No gasoline car has even the concept of SCR with DEF injection and DPF with regen operations. And modern diesels have enough sensors to keep even the best computer processor working full tilt monitoring and adjusting the parameters. For most of the time with gasser emission growth curve, the most technical thing going on was electronic ignition. Most of the bugs had been worked out of emission compliance by the time computer controlled gas engines showed up. And emissions equipment failures on a gasser might generate a check engine light, but hardly ever will the ECM derate the vehicle to a crawl or shut it totally down along the road. A totally different scenario with diesel emissions. It is more common than people realize how modern emissions diesels will derate and totally shut down over the least little sensor throwing a tantrum.
But the many of the heavy tow truck companies in my area dearly love the new emissions laden diesels. Has cause substantial growth in their operations having to go tow trucks into the shop due to emissions equipment issues. I know several of these tow truck operators and they are smiling all the way to the bank.
