Hey guys, looking to get a little more power and better shifting out of my 3.5 EcoBoost. I keep seeing 5 Star Tuning pop up on different forums. Has anyone here actually tried their custom tunes? Just want to know if it's worth the money before I pull the trigger.
Hey everyone, I'm looking to get a bit more pulling power and better throttle response out of my truck. Has anyone here used 5 Star Tuning before? I see them mentioned a lot on some other boards but wanted to get some real-world feedback before I pull the trigger on a tuner and their custom files.
