If you can get access to motortrend on demand, they just put out a test on sequential vs. bank fire injection. Really interesting stuff. They found that for performance (wot pull on the Dyno) no difference at all. Of course there may be better economy at cruise and cylinder tuning ability, but as far as pure power was concerned, no difference.
This is what i have been telling people for a while (at least anyone that posts their plans to go sequential on the FI builds) Only impacts emissions at idle/low RPM and for a home builder figuring the exact injector timing needed to do even that just isnt going to happen anyway.
Cant argue math. When you look at the injector pulse time at a given load/RPM and compare it to the time the intake valve would be open at that RPM for either system (batch or sequential) you have the same result where the injector is mostly firing on a closed intake valve anyways. Don't need a dyno to know there will be no difference as long as your are getting the correct AFRs.
