What are you hearing is the failure point on these units? The one thing that I have read is that the ECU's fail from heat since they are built right into the throttle bodies. I just wanted to see if you where hearing of anything else. I have been looking into the Holley Terminator, since the ECU is firewall mounted, be laptop tuned, and if I understand correctly, can be adapted to MPI if you want it in the future.
On another note, my main gripe with the current MPI units is the insistence to use a single plane manifold. They do it out of ease, not because it works better for a street engine in particular. Granted they still have good throttle response, but do give up low end torque. If you look at the OE manifolds, they are designed with long runner.
