I ran an Edge EZ on my 99 truck back in the early 2000s. It was a nice upgrade, I had gauges on mine(Boost and EGT) and it would never get hot with just the EZ. My Truck was a QC SB and it ran like a 16.20 the one time I raced it with the EZ on it which I didn't think was bad and people thought that was fast for a diesel back then lol.

If I had another one of those trucks I would put an EZ and a set of 275HP injectors in and call it good. That would produce good safe reliable power with little to no smoke.
