So i have a PC3 on my bike, loaded it with the map that is closest to my bikes set up. Runs good, probably not as good as it could, but have been running it that way for a few years.
Im curious if it would be worth it to take to a dyno. Would their settings make a noticeable difference? Or is the downloaded map from PC 'good enough'?
The shop quoted me 4 hours at their rate of $150. so only want to do it if i NEED to. might just search for a more exact flash map for my PC
Im sure many people have been down this road. and im sure its probably been beat to death in this forum.
vance and hines big shots, big sucker air kit, andrews 21 cam.

 

All IMHO....

There is no better tune than a dyno tune by a competent dyno operator... period...

However, on an OEM bike, a Stage I, or even a bolt-in cam (as you have), I also believe that in many cases, a good canned map by a reputable shop, will do well on a street driven bike..

There are a lot of variables in your question about getting a dyno tune. How good is the current canned map? How good is the dyno operator you will be using?

Whether or not you will feel any difference, on a street driven bike, is highly dependent on the answers to those two questions.....

I have a few bikes, and a couple friend's bikes, that I have flashed with canned maps from FuelMoto's and/or DynoJet's library of tunes. They have run well and I (they) have been very satisfied. I even had an HD Big Bore download, tweaked by the guys at DynoJet, and then flashed back into that bike, that ran very well. On my 124" crate engine, and a big bore with headwork, I only considered a dyno tune...

Based on my experience, to answer your question about the NEED for a dyno tune....

If the bike is (and has been) running well, the performance is good, and the gas mileage acceptable, I would say the dyno tune is not NEEDED.... But you are most surely leaving some performance on the table..

If your dyno operator is competent and experienced, the dyno tune WILL IMPROVE the efficiency, performance, and general manners of your bike.... There's just no way to know the delta change from what you have now...

With that said, only you can decide if the money spent would be worth it t find out...

 

This answer is solely based on my personal experience. With that said "hattitude" really know his ****.

On my 05 Heritage I did the Feuling kit below, Vance & Hines Straightshots, Arlen Ness Big Sucker and a PCIII. I rode the bike for about a month with the canned map from Fuel Moto, I felt as though there should've been more after all that work. I scheduled an appointment with a tuner. Dr. Dyno out of CT, this guy gets great reviews and came highly recommended. In the end, $300 and about an hour later he rolled her off the trailer. Let me say this, WOW, I could instantly feel the difference in performance, I mean seat of the pants performance and my fuel economy increased. My goal was to achieve a low RMP pull because I tour 2UP a lot, although we rarely hit the highways, but now and then we may be on a short stretch I need to hop on and off, and that low end grunt merging into traffic really helps. I'm very pleased I had her tuned.

Dyno for sure. Good dyno performed by a good operator is hard to beat. A good dyno does not necessarily mean higher numbers but if done correctly the bike will run smooth.
