Do a search for 5 Star Tuning on this site and you will have couple days reading. I have a Sept 2015 F-53 18,000 lb chassis with 6-sp. The engine was ok but the transmission shifting profile was terrible. I worked with 5 Star to get the shifting in normal and tow/haul to suit my needs. It took three tries to get a tune that fit my needs. 5 star stuck with me all the way, happy trying to please me.

If you are looking for a notable power increase or better fuel mileage a 5 Start tune, is not what you want. If you want would like different shift points and a more responsive throttle pedal, then this could be your answer. I am a very happy customer after 4 years and 27,000 miles.
