Aeromotive voltage controller
I have twin A1000 pumps, the second will kick on under boost (probably at 9psi)
Cost really isn't much of a issue, long as it does a good job

It sounds like a descent little thing but its almost as much as a new pump itself so I kind of question its worth, it would have to extend pump life like 50% to pay for itself even in a few years.
But it does look cool, I'll give some credit there, it would look nice next to BigStuff3
No tuning issues since it is consistent and only active during a no load (idle out of gear) or a low load (idle in gear) situation. I tweaked a few cells where I typically idle in gear.
