Last fall mine was $250 for 3-4 hours with a SERT tune. My shop tunes, then test rides, then goes back on the dyno for the final tweaking. Of course mine was the first 08 they dynoed, so that might be why it took that long. This spring I took it back in with mpg concerns, so they retuned with milage a little more in mind, didn't charge me for the second tune.

 

I don't know what qualifies DrRandal to make such naive statements as he did above, but I gather from reading a few of his posts that he doe not wrench on his ride and really knows very little other than he paid to have a simple map made.

As far as charges go, some shops will allow you to buy a couple pulls on your bike just to see what what it measures for horsepower, torque and sample the air fuel readings. This can cost as little as 50.00 a pull to as much as 80.00 from some shops. Others will charge a flat hourly rate for dyno pulls and this can be 80.00 to 110.00 an hour in most areas.

When it comes to tuning, most shops will then allow 4-5 hours shop time for an experienced tuner to dial your bike in which equates to a half day and normally runs with rates indicitive of their hourly billing deck. Some tunes are simple and require a quick upload of data in combination to a tuning device being installed, and others require more tuning where an experienced tuner will adjust timing, fuel and VE tables to arrive at the bikes optimal power delivery. Unique builds other combinations can sometimes take a full day to tune where these bikes can build between 120 and 150 horsepower or higher and they are not simple to tune. Sometimes a half degree of timing at the right point can absolutely make or break a great tune, and very few tuners are around that distinguish this type of tune.

A good tuner is going to dial the bike right in and will often perform 40-50 pulls or more while making subtle adjustments to the tables. If you're looking for a tune, ask around about he best tuners in your area, and don't just drop it off assuming your getting an experienced tuner. Also ask when the dyno was last calibrated. Ask how many pulls they are going to run, and ask about the tuners experience. Doc is also a member of this site and I think he has some posts on the questions to ask before you have your bike dyno tuned. Never listen to anyone that say a tune should always be done in less than 2 hours as that is pure nonsense.

Quality tunes do cost more, but they should also deliver!

 

Way to go 10sencondHarley.You are soooo right!

 

Drrandall1 maybe you can post your dyno sheet with the A/F ratio so we can see how cool your tune is.

 

I paid about $500
Yeah its a little bit of money.&nbsp\\; But the nike runs great now.&nbsp\\; It was after I had my true duals installed elswhere.&nbsp\\; They didn't have the right air cleaner so they tuned it with stock then re-tuned it when I got the air cleaner I needed.&nbsp\\; Dyno time (the best I recall without looking at all the paperwork) was around 4 hours.&nbsp\\; This includes testing, tuning, re-testing, tuning more...&nbsp\\; They used a SERT but even with that and a good map it needs to be tweaked just right for every bike.&nbsp\\; Any yahoo can plug a cert into their laptop and downlaods maps and some people will be happy with what they get.&nbsp\\; Hell I might even just do that after my next few mods to see how it goes.&nbsp\\; Anyway, it runs SUPER and I am very pleased with them.&nbsp\\; Oh, this wasn't at a dealer by the way.&nbsp\\; I think I will probably only take my bike to them for services and warranty work.&nbsp\\; The shop I am using is small and more user friendly than HD (High Dollar).

&nbsp\\;If your looking for a excellant tuner, and you can't find on in your area, Ed will hook you up. He's in Dallas, but well worth the drive!&nbsp\\; Here's a link to his site...

&nbsp\\;
&nbsp\\;He did my bike a couple months ago, and it's never run better!&nbsp\\; Smoothed it out, and runs cooler too..
&nbsp\\;

 

Ed from The Dyno Difference did mine as well. 5 hours, $395.&nbsp\\; I can't believe the difference he made with my SG.
Runs cool, no detonation.&nbsp\\; Dealer programmed an invalid SERT file on my bike.&nbsp\\; Popped and banged with every decel.
Rear cylinder was so hot it was burning my leg on the right side.&nbsp\\; Wife wouldn't ride on it because of the heat.&nbsp\\; Gained 5 HP
and 12 TQ,&nbsp\\; smoothest running bike I have ever had, and there is NO heat issues now.&nbsp\\; Still amaze's me how much difference it made.

 

10secondharley. Have had no need to wrench my ride yet. I'm not being naive either. I even left a number to a Colorado dealer that has been around 35 years. My bike runds great. My dyno was free but the dealer does charge $150 for a 2 hour dyno tune and that is all you need. Gary Williams is the Service Manager and will tell you that. Now my bike is a 96 cubic inch. This could be a different story if you have a 103, 113 and so on. Here is my dyno after only 1.5 hours and runs great. No need for a 4 hour tune unless you got problems.

 

350 would be a median price to expect. any less and id wonder why...

 

This thread by Doc 1 ("5 Questions to ask you Dyno Tuner") is very good to explain why 4-5 hours is necessary for a thorough SERT tune:

&nbsp\\;
As for the original question, it would depend on what the bike has on it.&nbsp\\; If it's a pipe/air cleaner swap, 4-5 hours would be overkill for the typical owner&nbsp\\;since the improvements would likely be nominal after an hour or two of a common combination for which the tuner has a library.
&nbsp\\;
For a performance build, 4-5 hours would be normal and necessary.
