I'd discourage changing the jumpers on the EZ with the engine on or with ignition on.

The box doesn't seem to like it.

I've had it throw overboost codes from fiddling with the jumpers, or even disconnecting the CAN Bus to make the EZ just act like a boost fooler...

Well, it was worth a mention. I don't know much about how the ez works, but figured there might be a way to have in-cab adjustability. Even if you could flip the switch before starting there might be a benefit for those with larger injectors who tow.

 

i'm sure if you ask the boys at edge they would tell you if it's practical. also if it's safe to flip the switch under load. wouldn't hurt to know even if you never do it./...later
