What can I safely stack with my MP-8---I cannot delete the DPF---New York is crazy about emmisions.I do not sit in traffic ...My commute is 6 miles and I do not believe that my truck has ever gone into REGEN after 4100 miles?????I may not have known it though.This truck runs strong and I have never had a cel or any light.I do not want the Edge

Thanks As always Bill

I would not stack anything with your MP-8 if you are keeping your DPF. You will be in regen a lot if you do.

However if you are set on stacking I would use the Superchips Flashpaq or the Bully Dog Power Pup if you do not want the Juice.

The edge is really not that much more difficult then the MP-8 is to install. Actually easier. It will also tell you when you are in Regen. But as K2 said. I would not Stack if i had the DPF in place. You are just going to soot it up faster and put it in regen more often.

Hey Men

Thanks for your response...Is REGEN a bad thing ? It seems to me that if that is the purpose of the DPF...Why not take atvantage of it ?...Am I missing something ?

Correct, you won't hurt the truck but your mileage will be drastically reduced with the almost constant regen cycles.

Would a bully dog power pup or the mp-8 by themselves (not stacked) cause a lot more regen cycles? Also, would deactivating the EGR hurt anything or cause more regen? Thanks.

The ts and bullydog will increase regens if you are driving it harder to produce more smoke. They can help mileage if you drive correct, many have seen improvements. Im not 100% on egr but i think you are fine deactivatings it but i think it might throw a code

You have to delete the DPF before you delete the EGR. Deleting the EGR will throw a soft code just like deleting the DPF.

removing the EGR and not the DPF will not allow the Regens to happen correctly. The EGR helps remove the NOx. Also you will not get the heat needed to complete the Regens.

You can run a single chip fine with the DPF. You will not cause more regens if you drive normal. The more you mash the throttle the more soot you make. During Regen Fuel is injected into the exhaust stroke of the engine causing the poor mileage.
