I have been running ADM's twin pump setup for almost 3 years and 45k miles with no issues. I'm pushing just over 700 rwhp.
I've heard of a lot of issues with the Aeromotive pumps lately. I have built or been involved with a lot of Camaro high horsepower builds and I either use the ADM twin or the ZL1 with ADM's fuel pump controler, depending on the horsepower level.
Check with ADM, Andy's fuel systems just work, You never hear of an unhappy customer with ADM products or builds.
