Rusty I run the Holley Sniper TBI , has been great with excellent throttle response ,idle , no vapour lock on 35 degree days Cannot fault it at this stage. Have had it on this new engine 408 since feb last year, have put around 6000km . I think as been stated is taking your time to read the instructions and limiting the EFI issues and routing the loom away to avoid the rfi . Yes there’s been issues due to faulty parts but the amount of these systems sold out there out weighs the bad from good. And my fuel consumption has improved not heaps but better than I expected on a long run providing you don’t get your right foot into it.
