I have an 07 fx2 5.4l.. This is my first time to be on a forum so im learning as i go.. I have k@n and flowmaster exhaust.. Im trying to find the right tuner.. Im not trying to turn my truck into a race car because this is my primary vehicle and im not rich.. Im looking for the best and safest tuner with the most gain in hp.. Not worried about mpg... And i only run supreme octane in my vehicles. Im looking for a tuner with a good reputation.. Good customer service.. And that is durable.. Please.. Any opinions wil help.. Thank u all
