I have been reading this thread for a while and have enjoyed it. I talked to Fastman EFI over the phone a couple of weeks ago and he was helpful to say the least. I will being purchasing my EFI system for him. I talked to him again at Mopar Nats and he answered every question I had and offered to help tune my car thru my computer over the internet. Good Luck on your project, my 67 Dart convertible with thw 2006 charger 5.7 now with a XM Motorsports intake with a new billet throttle body, Frank Racing Sparrow cam, pack springs and 6.1 rods. I hope to install the cam package in about a week or two.
