A week ago i bought a focus ST with 25k miles on it, it has a full exhaust, bov resonator delete and solid steeda motor mounts. When i test drove it it ran good and strong but i started noticing that on boost i feels like it stutters and missfires like hiccup any ideas of wat could it be the...

Hey guys I’m just wondering should the logs “that are asked to be done from stratified for the custom tune” be done on stage 0 or stage 1 Cobb tune??

so Ive done a little research into the different stages and requirements, while using the COBB access port stages 2 and 3 say it requires a cobb front mount intercooler or equivalent, but when i input all of the parts Ive installed on my car it says i can go stage 3... there is an area where it...
