I tried both the dual carb tunnel ram set up and the single carb/Indy port matched intake this past season and there was very little difference in ET/MPH between the two. I've had the M1 W5 intake sitting around for over a year now so I'm going to give it a try. If I don't like it I'll put the Indy intake back on. Thinking I'll stick with the single carb setup for simplicity sake since there's no real performance difference.
