I recently did several upgrades to my 2011 ram 2500. I completely replaced the exhaust from the turbo back, egr and throttle valve delete, new cold air intake, and a predator 2 tuner. My problem is a regeneration has now come up and it won't clear on the tuner. I'm sure it is because there is no longer a exhaust filter or cat and hence no where to plug in sensors. I have seen this exact upgrades done on youtube which is where I got my ideas. The issue is they do not address what to do with the sensor plugs or how to get around regeneration. Please help as I cannot drive it.
