Nowhere in the instructions do they mention shimming the relief valve.
2 electrical connections that fit between the factory harnesses and the scorcher!
The third electrical connection is to the battery!
It raises boost, adds injector duration.
Helps throttle lag and improves efficiency.
More like the old van Aiken boxes in the early 24v engines.
That box only corrected the ridiculous timing placed on those engines.
I know, I had a 98.5 24v and after that van Aiken box, the truck was a completely different animal!
It doesn’t seem like some of the old over fuel boxes.
If using an blue tooth device, you don’t even need it run wires into the cab!
This unit seems really interesting!
Just need to save a few pennies and I think I’m there.
Anyone own one??
