E98 2.8L Duramax DPF Removal for Race Purpose

Hi Guys we are building Diesel Drag 2018 Colorado so it is not registered, has anyone here done a DPF delete on one? we can set all the DPF settings in the DTC section to NO REPORT but after a little drive it will still smoke hard out of the exhaust. It has no DPF maps or switches that I can find or see, any help would be great thank you.
Also has anyone found a larger bolt on Turbocharger for these engines?

It's never been possible to do this within EFILive, you might be better off asking on a Colorado forum if anyone has created what you need in some other software.

If it's truly not registered I might be able to help you figure it out. What kind of racing?
