Turn off EGR without removing any parts Mini Maxx

Are there any down sides to Turning off the EGR without removing any parts just through the tune in the Mini Maxx? Or do I need to do the EGR delete? Thanks for the advice...

You are doing your motor a favor by tuning the truck and turning off the EGR into your manifold. However, EG still flows through your coolers, and there is always potential for mechanical failure while they are present. You aren't harming anything by shutting it off; however for longevity purposes, EGR deletes are the best solution. PerformancetruckProducts sells a good kit. It will be my next mod.

The only reason some folks keep their EGR coolers are due to emission control inspections--unlike the DPF, it's a tougher job to (8 hours or more) add/remove the coolers than the DPF (3 hours easy).

Hope that helps.

Another issue of shutting off the erg without removing it. It will carbon up and stick shut. There are tunes that cycle the egr at idle and will help prevent this from happing.

i think its been shown time and again that after returning to stock, a stuck EGR will free itself in a short time.....

Thanks for the advice guys, It will only be for a short period of time until I do the full EGR block off. Just wanted to know the general thought...
