Single Plane vs. Dual Plane with Sniper

Just wanted to see if anybody that is running the Holley Sniper EFI has seen any difference running a single plane over a dual plane when it comes to tuning the EFI.
Don't the instruction from Holley say to run a single plane intake with that throttle body injection system?
I bought and installed and then did engine dyno tuning on it for a customer several years back probably 12+ yrs ago so that information may not apply to the units their selling today.
I told the customer to do the final tuning in his car due to the exhaust system and the engine dyno being wide open headers during that break in and initial tuning. I told him to run it in the open loop initially and once it ran like he wanted it to switch it to close loop to lock that tuneup in.
