Indeed, some dynos will read differently than others. DynoJet units are known to be optimistic, wheras Mustang units are known to be conservative. Depending on the dyno, you may or may not get a completely accurate reading. Special pricing for dyno pulls, such as at large track events via a mobile unit, or on a promotional day at a local performance shop, are likely to be optimistic.
Few people are going to brag about a dyno number that's lower than they expected. However, they'll be talking to everyone when they "discover" that their car makes way more power than they thought. It's just better advertising. For the most part, a dyno is better used as a tuning tool; something to mark the increase and decrease in power as you make adjustments. Getting an "official" horsepower number is cool, but it may or may not be absolutely accurate. The often overlooked benefit is that it allows for the driver to know optimal shift point for each gear as it shows the powerband and one can use such graph to calculate when to shift according to each ratio to maximize the usage of power available.

This is fascinating stuff I would have guessed dynos were calibrated based on some SAE type standard or such. But in reality its more like women's dress sizes where the numbers are fudged to make you feel better depending on who is testing Darc Weingarte Teacher.

How long does it take to tune a piano? If a tuner takes less than 45 minutes, you may want to look for another tuner.
Without getting too technical, most of the 45 minute tuners are not giving a full tuning. If a pitch correction is needed, expect 2 and even 3 hours. Marharyta Vorogushin Beginner.

There are also additional costs for a tuning device or a tuning license for Fuel-injected bikes. Tuan Craig Beginner. What does a tuner do to a truck?

Step one: Find a proper axle. Step two: Lock down the diff. The solution? Weld the bus's differential. Not so easy, as they found:. We finally got the rear axle into our shop. Rigged the axle on a pair of jacks and had a discussion of how to lock the diff.
We saw a hose sticking out of the diff. Only way to lock it was at that moment to weld it. We started cutting holes in the back of the housing so we could weld through them.
Unfortunately the diff was sealed so we couldn't find the gears to weld. That meant we had to tear it apart. So we did. It was hell of a job and took three to four hours with rusted bolts, etc. And that tube? August 25, , PM. Most of these guys are quoting you "dyno rate" You'll need to pay the dyno rate, PLUS the cost of the tune. I know a lot of guys that claim they're good at it - few really are.
No tuning done, but you can pull out to the lot and make changes and get back in line. Not a bad deal if you ask me Whiskey for my men Originally posted by dieselgeek View Post. I've posted this on here before. As Scott and I know all too well, the dyno is just a tool.
If you use a screwdriver to pound a nail it isn't going to get you anywhere please don't ask how I know this Anyhow, like the screwdriver, it all depends on the skill of the guy holding the handle. And like the screwdriver, it can be a wonderful thing when used properly.
Worst case?
