How much HP was the tune suppose to give you? From their ad it looks like 40-55 hp which would be very noticeable. I would get a base line of your performance now from 40-60 mph at WOT and then test again after the tune, this way you can see the actual gain in performance. Most of us don't have access to a dyno. Does your engine have any other performance mods like headers or previous ECM mods?
We do not have any other performance mods other than the Ultratune. I asked Brazel's if the Ultratune was going to be applicable without having other items such as Banks mods. They assured me that it would be a noticeable performance difference even without Banks. I have no way to measure any gains unless their ODB connector gizmo can tell me. As I stated earlier, PERHAPS there is technically a gain in performance by the numbers, but nothing that I can tell by driving it so far. I was hoping that it would not need to downshift at the slightest overpass inclines, but it still does. Just calling it for what it is right now. We can't tell any difference at all. But YES BRAZELS HAS BEEN VERY NICE AND HELPFUL.
I was maybe not clear on how to measure gains, but all you have to do is measure the time it takes to go from 40 to 60 MPH with your foot to the floor. Do that now to establish a base line then after the tune. If you make any other mods like headers, advanced timing etc you can see what each what the performance increase is from each one. I am guessing you would see about a 4 sec reduction off your time if you are getting a 40 HP increase. A dyno will measure the HP increase but this will measure your actual performance increase. Good Luck and I hope you see something better.
