How Do I Load My Tune To My Device? NOTE: Before connecting your device to your PC, let's make sure you have the Device Update Software installed. Click here to download and install if you do not have the program installed.
1. Using the provided USB cable, connect your device to your computer. (Allow roughly 30 seconds for the drivers to install)

How Does The Tuning Process Work? Below is a step-by-step overview of our custom tuning process.
1. Plug your device into the vehicles OBDII port. The device will automatically power on.

2. Select “Program Vehicle” on your device and follow the onscreen device prompts for key cycles on and off.
1. The first time tuning your vehicle will take some time. The device will save your stock file in addition to tuning your application.

5 Star Tuning Guys ???

I have no complaints. I am very satisfied with the stock tune on my 2017 E450, V10, 6 speed.
I don't tow a brick house behind me, just a car with wheels. If I can only go the minimum posted speed up a hill, that's OK, I'll use the truck lane.

I don't need more power, faster throttle response or any of the other claims the tune offers.

We still have the group buy open at the current price through the end of the month. In December the price will change.

Currently, SCT also has a $40 rebate on the tuner that you can combine with our offer.

The RV community certainly is an interesting market. Other car or truck guys would think nothing of dropping tens of thousands of dollars on mods or "toys". But you can't even give away tunes on here.

The car/truck market is an easier market to offer tunes to sample as many have tuners hanging around from Mustangs, Cameros or other race-inspired applications.

because people dont think 5 star works. i didnt think so eather but i had to do something with my V10 it was shifting all the time noisy and screeming at the site of a over pass.
i couldnt use the cruse much witch i like to do. with the 5 star tune it has all been fixed. you have to call them and tell them what you have and what you want it to do. the people are very helpful on the phone. after 2800 mile trip i wanted a little more torque i called them and asked what they could do. with in 4 hours they emailed me a update tune works great.

I was into an alignment shop to have some work done recenty. When I went back to pick up the rv the tech that did the work took us for a drive to show what he'd done. When I took off from a stop light he asked what I did to the engine to get it to be so responsive. He said another tech had commented to him that just a blip of the throttle produced more uumph then they'd experienced with other V10's. I was pleased to hear that as I'd only driven the RV once without the tune.
I've said this many times. I've had many cars, none of which were ever "tuned", but the first thing I bought after bringing the rv home was the 5-Star tune!

That's exactly what happens when you modify the stock calibrations so the throttle goes wide open when your foot isn't even pushing the pedal down half way. This in no way increases power, it simply gives the illusion of a power increase.

I understand that you feel it's voodoo, (and it just may be) but there is a difference that I feel was worth the money. (and, yes, I've read your other post trashing it.)

Its not voodoo.
5 star states that one of the first thing it does is re-programs the throttle response. Its in their advertisements.

Just pushing down the pedal further, faster, when starting off will achieve the same thing.

It also changes the Ford stock shift ranges for the tranny. I got it, with the discount, for my 2012 Itasca Impulse Silver 31RP (F-450 6.8L) and am glad that I did. I think it has helped in these mountains and hills of NC.
