Thanks, well now I can start looking, and as far as dyno Ha $600 here so no way so I am getting the service reports on this so I can see what has been done and then proceed because the way it is its embarrassing It isn't auto tune!!!

By 'stock' maps I am referring to the ones that the tuners have available for downloads, not the one that came with your bike. If you have the stock Harley ECM, then they can change the maps (I believe that it's a package that you have to buy) or they can do a dyno and change the maps (an even more expensive package to buy). You can also buy a Power Commander or something similar which is a piggy back fueler module used on Ebay that you can then download maps for and accomplish what I was talking about in my previous msg.

Even after installing "generic" (unless they built teh map with a bike just like exactly like yours) maps , you should have it dyno tuned to tweak the map to your bike for teh most efficiency. If you went PC, have a POC guy tune it, if you went MT, have a MT guy tune it.

I went through that with my dealer when I had my race tuner. I put in a 105 kit from AMS then the first thing I did was replace the race tuner and ECM with a thunder max with Autotune. I've had it a year, my bike runs like a top and it is tuned 100%. It's pricy but if I ever make a change with pipes or whatever it will tune it in. I never have to hop on the dyno unless i want to see how much jam I got.

Here is the truth from my perspective. First, whether to dyno or not depends upon your attitude about how the bike should run There are NO stock maps that will give you the best performance for your specific bike. Period. They have a safety factor built in and unless you have autotune (a closed loop O2 sensor driven AFR) they will work but may or may not deliver what you expect. You can also tune them for more power or more mileage (which is sometimes accompanied by decel popping) through your laptop and/or a dyno.
If you don't have an autotune setup, and if you just want to make sure that your new exhaust air/cleaner system are compensated for and don't make your engine run too lean, you should use a stock map.
The HD version of autotune requires a trip to the dealer for changes in maps according to the HD catalog. Other manufacturers that I am familiar with have maps for downloading that are a good place to start from. If you don't have autotune (i.e. wideband O2 sensors) and you are a do it yourselfer, you can read a lot about AFR and the software that comes with your ECM or ECM piggy back and tweak the settings using a laptop until you are happy with the results by doing it 'seat of the pants'.
If you don't have autotune and you fine tune the bike to your specific locale, if you travel long distances over changes in elevation and temperature you may find that adjustments are needed. Some piggy back fuelers have a quick adjust button that you can push to compensate for this situation, assuming that you can get to the module readily.
Here's what I'm really saying:
There is nothing in this world that is free.
You always get what you pay for if you know what it is you are buying.
The only way to save money is to have the knowledge and capability to do it yourself.
Trust is earned and should never be assumed.
A custom solution requires a custom attitude.

Well i decided to go with the v&h fuelpak. Got a new on eBay for $100. Going to put it on first thing in the morning. This seemed to be the option that made the most sense in my situation, since I know im not going to be doing any engine mods. Plus it was hard to turn down that price! Thanks for all the help guys!!

Never cease to be amazed at the things people try to save money on....they will spend a couple of thousand on useless shiny cosmetics...but think they are doing a great thing by spending only $100 on questionable engine management electronics....

I presume you have V&H pipes on, or found a "map" on teh V&H website for your pipes. Fuelpaks are not user tuneable since V&H won't tell anyone what the number sequences represent (except for 19).
