Here's what I am convinced of; the Ultra Power upgrade provides more horsepower. The dyno showed that my 8.1 is now getting 324 horsepower AT THE REAR WHEELS! That's good in anyones book. I am also convinced that Brazel's excels at service. Alan, a service tech at Brazels, knows what he is doing, treats the customers with friendly respect and oozes honesty. But I am not convinced as to the mpg claims. On our return from Alaska, I picked up some pinging. I called Mike and we set up an appointment. We were ushered right in, made to feel comfortable, made aware of every step of the process and had the program reloaded twice until both Alan and I were satisfied. The performance is obvious but my mileage is only marginally better. I have a light foot and purposely kept the speed at between 60 & 62. I used all six gears when I could and coasted when possible. Maybe now that the programming has been redone, time will yeild more mpg, but for now I am satisfied and am thankful thet Brazel's is an outfit that stands behind its products and work. Thanks Alan and Mike.

Craig, you are correct in the Ultra-Power not necessarily increasing gas mileage. At least not much, as in maybe not enough to notice. But, you are also correct in the power gains, this to me is it's major gain.

Probably the biggest factor that will increase your mileage will be break-in. Your signature indicates a 2007 moho, and also you are pulling a 4X4 Ford Ranger. With that weight you will definitely horse the moho down abit.

When I did the Ultra-power and CAI the change was, like you, in power. A very limited, if any mileage gain. However, when the mileage on the drive train approached 11,000 to 12,000 miles I've definitely seen an increase of a mile or two. Not much, but what the heck...

I was told, don't know if its true, that the updates based on the January GM changes will result in better mileage numbers. The jury is still out as far as I'm concerned.

I thought it was just me....I have since put on several thousand miles since my UP install in June, and there is absolutely no MPG gain.....

Oh well....I'll take the power and forego the MPG claims....

You both have the same coach all be it different sizes and chassis. The milege I get is 2 mpg better than before I had the UP done over a year ago and has held at 2 since I had the upgrade this summer. I have only kept a check on milege on long trips with muiltible fill ups.
One of you should be getting something better.
I'm 38' and close to 22,000lb's without a tow.

Tom my milege was in the 6's. Going to Tenn. in 06 got 6.1 and 6.9, same route back got 8.1 and a 9 on last leg of trip home.
I have kept track this past year and its been holding in the 8's with alot of the driving in CC which is great just sit back and steer.
I had the tweek on program in Branson and I have been checking its still in 8's.
Mike did say it would stay the same with improved program.
Right now I have 23,400 miles on coach due for trans oil change.

Well I don't know if it's the Ultra-Power or the fact the engine's getting broke in. But with 14,000 miles on it now it definitely has more power and gets between 1.5 & 2.0 mpg better then it used to get. Especially in mountain driving. Just recently put 443 mile trip which included hard mountain driving over 2 passes, one which was long and steep. Pulling our 3600-lb Colorado Pickup and loaded with full tank of fuel, had a little over 1/2 tank of water and the pass dragged the speed down to 30 mph and shifted down to 2nd gear, RPM was close to 4000. When we got back home and filled the tank it showed 7.3 mpg. 6 mo's to a year ago this same trip would have yielded about 5 to 5.5 mpg.
