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.

Log InI've been running their 87 performance/tow tune for about six months now and it's night and day. The throttle response is so much better, and it finally fixed that clunky 10-speed shifting issue I was having. Highly recommend them.
Seconding this. Their customer service is also top notch. I datalogged my truck after loading the initial tune and sent it over to them. They tweaked a few things and sent a revision back the next morning. Truck pulls like a freight train now.
Definitely worth the money. I got an SCT device with a couple of their tunes for my Super Duty and it completely woke the truck up. You won't regret it.
