Meth Injection Nozzle Placement

[Amfchang]

I have the AMS Charge Pipe and It Seems The Only Pre-Bunged Nozzle Placement Is In The Throttle Body Spacer Instead Of Others Being Placed Well Before It In Mid-Charge Pipe. Some Have Told Me To Just Drill Into the Pipe Instead Of Using The AMS Throttle Body Spacer Bungs. Any Info On Why?
