Holley vs ProEFI - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Looking to get an aftermarket ECM and have it narrowed down to a Holley Dominator system and Pro EFI.

I need transmission control, boost control and data logging, along with all the safeties that come along with that.

Looking for suggestions from people who have used either product. I solely use the car for drag racing and am currently on the stock ecm making well over 1200+whp.

Car is a 2015 1LE with twin turbos, RPM Level 5 4L80, etc.

I have a Holley Dominator in my other car, a single turbo / LS combo in a '67 Camaro.

I'd go Holley. I know only a handful of folks running Pro EFI and some of my tuner buddies don't like working with it.

I been tuning mine with a buddy, very easy to learn, I love it.

I noticed you are in the DFW area. If you still go to the track send me a DM. We run the Holley Dominator on our turbo 5th gen. We just got it running and getting it dialed in now. I had Pro EFI and after speaking with a handful of buddies I sold it for the Dominator and love it.

Just made the switch from ms3 to holley dominator. I'd go with the dominator hands down.
