Does anyone have any suggestions on an engine management system that i can use? All the tuners offline will not write me a tune that will allow me to run my truck without the EGR system. Thank You

We have done some 2.5L ones and able to run a lots of engines with our diesel management system but canbus communication will be problematic and most cars we do are or motorsport use only.


If it’s a daily drive better find a someone that can hack your ECU and remove the EGR function.

That's awesome, thank you!
