Yeah, lots of poeple find it hard to tune the 24's and MAF perfectly. The Cobra computer and MAF is the ideal components to use from Ford when using the 24's for the best tune. But then again that's more money. I use the 24's with a C&L 73mm with no problems and excellent idle. I guess I got lucky. Most don't have many problems at all but there are a few that have stumpers. Good luck!
