I was reading on the Frontier boards about the Apex-i SAFC and its got me thinking about adding that to the lineup. At the rate I am racking up the miles my warranty will be gone by december! So much for buying a new vechicle! Anyways....anyone in the Nashville area know of a performace shop or just a shop period that has a dyno and could help me tune the AFC? Anyone with an X added the AFC yet or if I do it will I be the first? Thanks for any help!
