So I had a 5star sct hand held for my 13 ecoboost with the 5star 87 performance tow tune. Noticed a real big difference once installed. I have since got a sct livewire from 5star with the same tune. This one I recently installed feels nothing like the previous one... Strange... I'm hoping they accidentally gave me a 87 economy tune instead of the other. Either way it's definitely noticeably slower. Raced a friend with first tune and left him behind 3 lengths and still pulling. Same truck today same conditions outside and I pulled him just to the rear of bumper and then he started pulling ahead of me. Drives fine shifts fine just don't have the get up and go I had before. I emailed them so hopefully they will get this figured out. Live the gauges with the livewire though

 

what did you do with the handheld tuner?

 

Don't have it anymore

 

Hopefully Mike will get with me after xmas
