Confused about Hp gains

[Longshot270]

The programmer was saying I was running 16.1. Then I went to the drag strip and the best I could get was 17. There are many small errors that when put together throw off the entire calculation.

Also if you run with the truck stock and then programmed you'll probably have different times from different tire sizes and such. The programmer can only assume how fast you are going from what you say the tire size (and no single tire size is correct all the time) and gear ratio are. Like I said, many small factors build exponentially and throw it off.

Lowdown, Oh ya, it feels much faster and more power. I was just expecting better performance.

Longshot, the factors what you said which play into the results make sense. I'm going to do some more runs and see if anything changes. I did it again and it came up with 272 estimated Hp, which is much better.

And what was the difference? Was it on a smoother road, different time of day, different temperature or something like that?

It was the same road but I just had a better take off and i also looked up the weight of the truck again to make sure it was correct, so it could of been a my own error.
