Holley Dominator boost controller question

Holley Dominator boost controller question
I was planning to run a factory ECM tuned with HP Tuners on a boosted 6.0 with an AMS1000. I have been looking into buying a new Holley Dominator system instead but I am not sure if the optional boost controller feature will be as good as an AMS or Boost Leash. My car is a 275/60 car and will be making 1000hp+ so I like the 6 stages of boost control with the AMS1000. Has anyone tried it on their car and if so, how adjustable is it?

I run 2 of them, one for pressure and one for bleed. CO2 setup, little 25 dollar tank from harbor freight and robbed a regulator off of an old air compressor.
Mine uses two outputs and one input. two PWM- and one sensor input.
EDIT: You can also download the Holley software for free and play it as well. I just started using mine last night messing around on the transbrake in the driveway, only messed with the TPS based ramp and time based for the moment, i can see myself getting into the MAP and Dome controlled in combination for control though.

The directions are long and complicating, but if you read the quick and dirty startup guide it's much easier to understand.
Basically once it's wired up just start adding dome pressure (if using a fixed source) and plot how much dome pressure it takes to make XX psi. Then you can go in there and pick how you want to control boost. I use boost by rpm and fill out the graph to the dome pressure required to achieve 13 #'s of boost.
Hope this helps.

It does seem that way but once you get into it you will realize how intuitive it is. The best thing to me about this system was the ability to dial in the controllers without the car running. Makes you feel very confident on that first pass.

Wow, some great info and feedback! Sounds like I will be ordering one up this month and selling off the HP Tuners and ECM I bought.
I see you can run low or high impedance injectors with the Dominator. Any reason I shouldn't save a buck and get the low impedance injectors? Planning on 160LB injectors for the E85.

Depends on how you want to set it up. You can use a 3 or 5bar MAP sensor you can also use a 100psi pressure transducer. What will you be using to send pressure to the domes with?
CO2? On board air compressor? Or just manifold pressure? Essentially, however much pressure you will be sending and regulating will determine what sensor you need for dome pressure sensor.

Its very good IMO, but I havent used an AMS.
I have mine setup with a small air tank in the trunk, I have 10 psi springs in the gates & it takes 15 or so psi to get 21-22psi in the motor.
I have used both a holley 3 bar and holley 5bar as the input for the boost control.
I use Boost Vs speed on the street and boost Vs time at the track.

To the OP, I use a 3bar MAP sensor as reference. They are cheap and effective and have enough resolution for your plans.
