Well yeah, I assumed the guy meant hp gains. Apologies, Sean, if i've done you a discourtesy there.
Best off welding/filling the EGR ports, removes any cause for turbulent airflow where the system used to be. Most people blank their EGR's in conjunction with disabling the actuator system because - at the kind of mileages we're seeing on these now - they're often partially blocked/seized open. Definitely worth making doubly sure imo.
Ideally you want to have the whole thing taken off your map, but then we're talking more money, maybe get it done with the stage 1 map.
