While they may work it can't be without a trade off. for example when I bought my truck with the V-10 I had to sign a paper acknowledging that I understood that use of any aftermarket tuner would void the power train warranty hence the many web sites dedicated to hiding their use from the dealer when the engine goes in for repair.
They do work well on diesels however most, for gassers, require the use of premium fuel; although I have no first hand experience with the unit mentioned by the OP.
I do find it strange that some computer programmer can find the magic hidden power and fuel mileage that the manufacturer couldn't. GM or Ford would sell their soul for one mpg better mileage or more HP and be advertising around the clock if it were that easy to do with no risk.

I have the newer 362 HP, 30 valve V10 w/5 speed Tranny in my Class'A'. Other than K&N Ram air Intake, Full aftermarket headers, removal of the Catalitic converter & Full flow, Duel exhaust, there's nothing U can (SAFELY) do better than what Ford has already squeezed out of it.

I was a bit reluctant at first to go with a Tune but I separated the wheat from the chaff and really decided that what I wanted was some better shifting patterns off the tranny. I am not expecting any change in MPG, just comfort. One issue I can't stand is when the tranny downshifts and the RPM's jump into the 4's and 5's. I have been told the 5star tune will remedy this. I'll find out soon as I have a trip planned to try it all out.

I think what they made you sign will not hold up in court. The laws consumer protection laws are written such that, in case of a warranty claim, the burden of proof lays with the manufacturer of the vehicle and they must demonstrate that the modification was the cause for the failure. By making you sign these papers, they hope to discourage you from tuning, but you cannot sign your rights away, no matter what they make you sign!
Concerning the programer finding some hidden power. the factory programs the computer to be able to work under all kind of conditions, but since they try to do all, nothing works really well, and that is where the tuners come in, specialize the program for the specific use.

That would be a good argument IF we were talking about a standard vehicle. The reality is that Ford and Workhorse made bare chassis for numerous different coach suppliers. At the time it is made, neither Ford or Workhorse knew if the chassis was going to be used on a coach with a gross weight of 10,000 or 25,000 pounds, 25' or 35'. For that reason, the factory ECM's are tuned for a middle of the road situation that may not be ideal for the finished coach. What the custom tuners do is adjust the ECM parameters for the specific weight and gearing used for your coach. They will also adjust the transmission shift points for best performance and economy. You are right, Ford and Workhorse would adjust these things at the factory IF they knew exactly how their bare chassis would be used. Since they don't, it is necessary to go to outside tuners to adjust things once the coach is on the road.

Quite the contrary on premium fuel requirement, the 5 Star tune that came for our gas coach was for 87 octane fuel.

Hi All.
Just something for you to check out before you buy anything for your Motorhome, Yes, Tunner/Programmers do a great job on Diesels, I have fist hand expereince. Gto grat performance and more MPG easily. But I also did a Chip on a Gasser, and it did improve performace some, but no increase what so ever in MPG. Now if your looking at shifing better, then check into a "Banks Trans Command", for your Transmission. I have the "Banks Trans Command" on our 460 EFI Motorhome. It did make a pretty good differance. It doesn't shift as often, espically at the slightest hill comming up. The shifts are much firmer and quicker, not rough and doesn't slam into gears. Also helps to keep the Torque Converter Locked up better. This might be a better way to go for your Transmisson needs. Worth checking out at least. Good Luck. Happy Travels. Dan & Jill

If you can increase peak HP 20% (typical for tuners plus headers plus intake modifications on the 2-valve V10) you can expect maybe a 10-15% increase in your maximum speed on any particular grade. You have to be willing to climb that grade running full throttle at peak HP rpm. Thus if you are now getting 50 mph climbing particular grade at full throttle around 5000 rpm, another 60 HP might get you 55 to 58 at 5500 to 5800 rpm.
Tuners alone won't get you 20%. You need the headers to re-tune gas flow to raise the torque curve in the upper rpm range, for a higher horsepower peak. The tuner can adjust timing, dump more fuel into the intake manifold all across the rpm range, and raise the rpm at which fuel gets cut off, but it can't change full throttle airflow.
