edge
the boxes don't work as well on the 6spd ETH H. O. engine.
from what I understand an EZ or Van Aaken will produce about 65 on a standard, and about 45 on a HO. even still it is a noticable gain and mine gets better mileage.
the HO VP-44 works a little differently, I think it has a higher pressure, but lower volume. I understand 60hp injectors will show up as 80 hp. check out the dyno's on diesel dynamics website. same injector, different HP between so and ho engines.
I have a Van Aaken box available (used 6k) I just bought my friends edge comp.
email me if you are interested. $270
oh and get a BHAF... I can ship him 2 for $70
