new to the dmax world few questions
 

just sold my 06 cummins and bought a 08 dmax. ive worked on them several times just nvr owned them. whats benefit from just dpf delete pipe and full turbo back and the egr block off plate vs full delete. I already have efi from the cummins. I plan on keeping truck low profile just wanted some input on mileage and power differnces. thanks ahead of time.

the block off plate allows you to quickly return it to stock if needed. full delete removes unnecessary junk off of the truck and frees up more room under the hood. it also gives you an option of upgrading the exhaust size for better EGT control and less back pressure while the DPF delete pipe remains the same size

if i had the money and did not have any emission testing where i lived i would do the full delete with at least a 4" exhaust

Id definitely do exhaust. MBRP or Flo Pro would sound good on it. And if you just want a small tune bully dog is goodor banks has some good ones. If not EFI live is sweet to have
