EFI question

My project recently switched directions. I was going to convert my 408 to EFI with Megasquirt, buy I acquired a 5.7 so I'll be using this instead. The good thing is I can still use the MS3X controller with the 5.7.
If you don't want to build the controller or harness, check out efi source. They have a plug and play kit for G3 Hemis at a really good price. It even comes with a base tune.
