5 Star Tuner

This is for all the guys using the 5 star tuner, I'm kinda on the fence about buying one, my question is what year are you running, as I'm looking at installing on our 2014 377xl. What about issues with Ford warranty and what great advantage has it given. As for me to purchase I would be looking at around 575.00 US dollars shipped to Canada.

I am with you on the fence I have a 2012 378XL and been thinking about installing before our 3 month trip this June. But want to hear from anyone that has it installed. Not trying to hijack your thread.

I have it installed on my 2013 Coachmen Mirada 35DL. It doesn't give you any more mpg than stock, but what it does give you is reduced downshifts, better throttle response, and quicker shifting overall. It just seems to be a much more powerful motor with the tuner installed.

I'm running it on our 2012 Lexi 283ts. It was designed to do more to improve the tranny shifting than to provide more horsepower.
It does increase hp maybe 10-15, but the real improvement comes from improving the shift points.
When going up a grade as on an x-way, no more dropping from OD into the "screaming third". Now it maintains OD, and then will drop into forth, and then into third, if needed. I run my cruise control alot, and find the tranny maintains its set gear selection a lot longer going up a grade.
Also, when cresting that grade, tranny used to stay in the lower gear for several hunderd yards. Now, it shifts back to the higher gear much much quicker.
Acceleration is improved a bit. You will notice it when under hard acceleration like entering an x-way on ramp, or passing. Not gobs of HP, but noticable.
If your expecting big increases in HP and performance, you might be dissapointed, but you will definately notice the improved "driveability" of the rig.
Happy customer, and whould buy it again.

There is a function on the tuner that allows you to return the computer to stock mode. Not sure if it leaves a "footprint."

SCT claims that it does not leave a foot print. I guess we will find out somewhere down the road, I just installed mine after a lot if soul searching and worry about my factory warranty because thus is a brand new coach but I hated the way it shifted on all the hills around southern Ohio and northern Kentucky. I also travel a lot out west, Co, Wy, Sd and Mt. Time will tell if it was worth it or not having owned four Ford Diesel trucks I have always be afraid to use a tunner because Ford is real strict about there use. Since this one is not really a power tune but is mostly for smothing out the transmission shift points I am hoping it will be ok.

+1. I followed the same logic when deciding to do the 5 Star. Used it on our trip from Maryland to California and back--very happy so far. The "sweet spot" for me is between 65 and 70 mph on the highway. Set the cruise and unless there are no "big" hills, I get no shifting until it drops below 62 or so. If I see it starting to drop that low, I switch off the cruise and feather the throttle to keep it from dropping into 3rd gear.

But I'm guessing that the XL might have a different gear ratio than the 364.

Seems the 6spd transmission has fixed most of the "gear searching" issues, no? Full disclosure, I only have 2 hours driving time on my 364 but it was a pretty good mix of hills, curves and highway driving and it was pretty smooth. My father in law has a 2015 Fleetwood Storm with the 5spd and mine seemed a lot smoother and more quiet than I remember his while on our road trip to FL over the winter.....

I have one on my 02 Excursion V-10. 5star really knows what they are doing! It's not all about power with them. They want their tune to be an all around good performer. Their testimonials are all spot on. The newer V-10 are just as good with a tune. I believe the newer stuff is drive by wire. The factory program doesn't give you full throttle when you think you have it. 5star's tune gives you 1-1 throttle opening, meaning 100% pedal to the floor gives you 100% throttle opening. I think he factory only gives you 75% under certain conditions.
Mike at 5star will answer all your questions better than I could. He is very good with customer service and will answer any question you have.

So has anyone installed the 5star tune on a 2016 with 6spd transmission? Any improvement?
