I have the new updated unit and have had no issues, however I did not have any issues with the old unit either. Boost control is working great and the factory coils seem to be a non-issue now. I am only around the 1200hp level though.

I just got my Holley Dominator system for my 2004 Silverado. Are y'all running stock gauges with this unit or do you have to run aftermarket gauges?

That's what I want to hear. How long ago did you do this? I want to get rid of the POS coils they have.

I would like to try the plugs you have had success running on my setup which has been 9.6@144 on 19psi. would you mind disclosing the actual NGK# and I will go and get a set. Thanks.
