Hello all, Fairly new Harley owner, so ignorant about most this stuff. One question. i have a 2008 flhr and am going with Thunder Header 2 into 1 with falsee and a PC III plus V&H air cleaner. Do i need to still get it Dyno tuned?
Also, I'm going to have Rinehart slip ons available.
Thanks for the help.

 

Need to or should? Many believe for maximum, dialed in, individualized performance one should be dyno'd. Factor in costs, the dyno, the tech, others - you decide. Many ways to get it close, it's up to you my man... for many, $$$ is their focus.

 

I did all that stuff to my 2010 Street Glide when I had it. I figured with all those changes, the only way I would ever know that I was getting the performance that I paid for was to have it dynoed. Just my way of thinking.

 

To the OP....YES, you need to get it dyno'ed if it's FI (fuel injected). If so, you'd be making enough changes that there's no way to tell if your motor is running too lean without having a good tuner put it on a dyno. Without it being done it would be too big a risk for most, aside from the performance factor. While both are important, the aforementioned is most important. Do yourself a favor and give yourself the peace of mind that knowing your motor is not running too lean.

 

you should be able to get a canned map and skip the dyno. your combination of mods is pretty common.

 

If you have never had a bike dynoed you will never know the benefits of having it done! My old Glide is carb and runs like a dream and I reckon yours will too, if you have it properly tuned. A lot of owners will just mess around until if seems about right, but modern bikes cannot be back-street tuned like we used to do in the past, so get it done right. You'll be amazed at the results....

 

Thanks for all the help friends.

 

Agreed.

If you can find a canned map with mods close to, or exactly like, your mods there will be very little difference to a dyno tune.

 

A canned map from a great source beats a dyno tune from a tuner that doesn't know what they are doing.

A dyno tune from a great tuner beats a canned map from a great source.

It has much more to do with how great your source is than if it is a canned map or a real tune.

I have done business with three dyno tuners. One was horrible, one was very good, one was great.

This is an impossible question to answer unless you know how good your tuner is.

A canned map will get you close, maybe. It might get you spot on or it might be way off. The same model bike that came the assembly line immediately before and immediately after your bike are not exactly alike. Subtle differences in the form of tolerances and allowances make each bike unique, so the custom map that makes one bike run perfectly will not produce the exact same results in the next bike that is configured "exactly" the same way. So how can you achieve a great tune from a generic map that was built on another bike with similar parts? Do you want your bike to just run good enough, or run good? I will never understand why folks put the money into parts but don't want pay for a tune that will compliment those parts. If you're not going to tune it properly you Might as well just leave it all stock and slap on a 103 air cleaner cover, either way its the same illusion.
