I noticed NO change when I went to an AiRaid filter on my 03 6.0, well, except I don't have to pay 75 freakin dollars for a new filter ever again!!

SCT is NOT the only programmer that will do transmission changes, Edge does also. If SCT is still a flash programmer, leave it alone, the flexibility of INSTANT changes, little to no smoke, 4 gauges, and gobbs of power make the Edge worth the money.

UPDATE: I wasn't impressed with SCT Livewire website, or the Super Chips I used on my 04 GT. This is what my Edge Juice PLATINUM does for my 6.0L

Get a 3.5" down tube into a 4" exhaust, then you'll be cooking with grease!!
