I've read a lot of good reviews on here about the edge evolution. I also read something lately about recommending people to get gryphon now instead because "edge stopped allowing the gryphon upgrade" or such.

My 5.4 fx4 has the 35x12.50x20 fed's and I have the drop in Spectre air filter. I also have an aftermarket muffler, probably about to get high flow cats as well. so what settings should I set on it?
I apologize, I have no knowledge in programers haha!

thanks in advance!

 

Edge and SCT are two top brands for the f series pretty much. Won't need to adjust tune for just a drop in filter or muffler.

 

level 2 ... if you want to buy 91 oct gas...level 3
