$250 for Dyno Custom Tune Worth It?

maddhatter777 · #1 24th July 2007

The closest dyno is about an hour away. Is it worth the $250 get it tuned? I know it is the going rate but it just seems a bit much. All they are doing is properly jetting the carb right?

That and timing so that the bike runs properly throughout the whole RPM range.

IMO - if you've got a built engine/conversion, it's worth the money. If you're running all stock or a stage 1, save your money and do it yourself. You can get it really close with a little time and tuning on your part.

All I have is a set of troublemakers and a SE air cleaner. Nothing special. So I'll do it myself..... Thanks for saving me some money!!!

Well step one is to do a few pulls to get a base line.
Then adjust the carb as needed.
Do a few more pulls to see results.
Then readjust. Repeat as needed.
It could take them a good 2hrs to do, it could take 4hrs...
Plus parts, and what not. There not just jetting the carb.
If they are then your getting screwed. I'd stick around and watch if you could, its fun to watch your bike on the dyno. Depending on how you ride it though you might think they are trying to blow it up.

As noted in a post in the NRHS section, at the NRHS 4th party, Aaron tuned Phelan's bike for 7 more HP (phelans bike is a stock 1200S with stage 1 mods) and tuned another guys 98HP 88 inch bike for another 18HP! NRHS charges about 250 bucks +/- for a dyno tune. The tunes were on the house by the way, but even if they paid for them, the results were more than worth it.

A good quality dyno tune is going to cost you about 200-300 bucks but, if they are good tuners, they can extract a lot of hidden HP as shown in the examples above. Money well spent in my opinion no matter how stock or modifed your bike is.

Best $ spent...horsepower gain, rideability and insuring engine is not harming itself. My FI Deuce Stage I gained 11 HP and 16# torque....AND ....it was running great going into dyno. The tuner is way important to be satisfied with results...the dyno doesn't tweak it...the tuner does with help of OBJECTIVE dyno. The gains shown above are about twice what the parts alone added with a decent running tune...for about 20% of total cost. Throttle respose, mileage etc are ALL improved. And no I don't sell dynos...oh the 1200C is Stage I carbed and dynoed and runs right with the Deuce. John

If you don't plan to do anymore engine work, then $250 might be worth it if the tuner is really good. Otherwise you end up paying a lot of money for nothing. It's all about the tuner and his skill. If you plan to do more engine work, then I would get it done and have it tuned. That way it will be $250 worth of tuning instead of $500. It's only a waste of money if the tuner sucks.

I saw Dr. Dyno tune a bike for $300.00, and he added lollipop tuners to the shotgun pipes + rejetted the S&S carb. It started too rich with a torque dip 2500-4000 RPM, but left spot on AFR-wise with better low end torque.

Well I found out today my local dealer has a dyno. Good chance I'll be scheduling an appointment with them. $60/hr average 2-4hrs. Guys are "schooled" (dyno college) so it should be worth the cash. The only issue now is to think about adding any parts so I don't have to do it more than once!!! haha.

Another thing to do is ask questions. BEFORe they tune, Find out exactly what you're going to be getting. Find out what they plan on doing, ie how many warm up pulls? where do they start the baseline for the chart? how many pulls after changes?

Have some idea as to whats going to be happening to your bike...

Otherwise you can just look at em and say. "uhokay!" when they tell you your bike needs this that and the other thing. (ie dynojet, yost, new carb, ecu, etc.)
