I've heard about the air box tip. Actually that's about the only thing I have heard of, unfortunately. That & attaching aluminum dryer tubing to the air box and creating a type of ram air. But I'm not going to do that. My Mustang is my drag car...I was just looking for some free or cheap tricks or upgrades. So how is your gas mileage now that you have those 4.10s? Seems like it would take you through the lower rpms too fast, being that that is where the 5.4s make all their torque. How is it on the freeway? Does it tach pretty high, or does the OD make it ok?
