Hello everyone.

I am researching common opinions on performance upgrades for the 6.7 Cummins platform and want to understand how different tuning setups affect reliability, fuel economy, and overall drivability under real-world conditions, especially for off-road use.

I have seen conflicting reports about emissions removal systems and the ez lynk 6.7 cummins delete kit, and what experiences users have had with installation, tuning, and long-term maintenance compared to stock setups.

I am looking for honest feedback on benefits, drawbacks, and any issues encountered during ownership, and whether it is worth considering for dedicated off-road builds.

 

thanks in advance for any help
