2002 4.6l
Hey yall new to the forum was just wondering if there is a working progremmer gryphon yet out for my truck. It's a 2002 4.6l v8 k&n cai 77 series with a flowmaster cat back. If there is a programmer out again i was curious what kinda gains i will feel? will it be more significant than when i put on my cai? i'm reffering as if i did a 93 perf tune, thank you for any replies!
