I daily a 2010 fronter 4.0. I have long tube headers, custom Rockers, a couple little head tweaks, and 4 months worth of street tuning. . I'm 2 years into tuning this truck as my daily, and I still feel like I'm just shooting into an abyss and hoping the truck still runs lol. I'm just wondering if the 4.0 will ever get some love. . . Getting real world timing to match the file is harder than getting s Latina to make sense lol
