If this is who I think it is then I ran two trucks this past weekend at the Northeast Performance Diesel event with these pumps including his own personal truck. If I am correct, from what I saw, it is not smoke and mirrors but real performing pumps. I'm not going to claim to be a pump person, but the builder explained to me what he changed with hand made parts he fabbed himself. Both trucks ran as well the turbo's would allow. One truck made mid 500's with a very small set of twins and over fueled, and the other made upper 600's with a huge set of turbo's I never got fully on top of. That truck ran a calculated 770hp at the track based on MPH. Fuel only runs, no bottles.
And I love the idle... trucks seems docile and smooth off idle... but that idle...
