Re-map?
Im considering a stage 1 intake for my 08 street glide and i was wondering if im going to have to remap or if i can get away with leaving the stock map in it without causing an issue.

You will need to remap or it will run lean which is hot I own 2 bikes with Power Commanders and do not ever need to go to the dealership. If you have access to the internet to get the latest download, a laptop computer and a USB cable you can load your own programs

I would beg to differ, if all you are doing is putting a free flow AC in your bike will compensate, it wont burn up. Never seen a pic of a bike that burnt/blew up because of a free flow AC on a stock map

Harley dealers will charge you an hour to flash as well, so at that point you are north of $200. Many folks on this forum have done pipes, mufflers and AC and are using FL-Vieds with much reported success, and the cost of that is $119

Lots of different opinions on this. I talked to Steve @ Nightrider and he gave me the best explanation I've heard. Read up and make your own decision on if you need it or not. Personally, I did the ECM download on mine to update the timing tables but the download does NOTHING to update the Air Fuel Ratio. See his comments below:
Subject: FL-Xied10 Question
The HD Stage 1 download does not change the AFR table. That would put HD and the Dealer in violation of Federal and State emissions regulations. In closed loop, the ECM is monitoring the O2 sensor to control the fuel mixture under 4000 RPM and 40% throttle (steady state) or 95-98% of riding conditions. The engine is not 'technically' lean, nor will it go lean when you make exhaust and air cleaner upgrades. The Delphi ECM was designed to compensate for changes like that, and that information was even published by HD Engineering right after the new ECM's were released. This is all hype by the HD and other companies marketing department to scare you into purchasing EFI components that are not required.
Have you ever found anyone that has had an engine failure because they upgraded their exhaust and air cleaner? The answer is no, not unless there is another mechanical failure in the engine.
Now what is the real story?
Your HD engine is running at a 14.6:1 AFR, the same fuel ratio you car is operating at in closed loop. At heavy/full throttle, the AFR is 13.8-12.5, depending on RPM/engine load, just like your car. If you change your exhaust/air cleaner, the closed loop ECM will compensate and maintain the 14.6:1 AFR and through adaptive learning, the open loop AFRs are also maintained.
14.6:1 is not technically lean, although it is not an ideal AFR for an air cooled, V-twin engine. This is especially true when you are sitting on the engine. But this AFR is required to meet emissions regulations. Of course by richening the closed loop AFR, there are certain benefits you see as a Rider. Do you have to richen the AFR? Technically, No, the engine will run fine. Is it nice to richen the AFR? Most definately YES! but do not let anyone bully you into rushing into a purchase. No me, a HD Dealer or another vendor. It all boils down to how far you are willing to fall off your wallet to accomplish the richer fuel mixture.
The FL-XIED-10 fools the ECM into thinking the engine is running leaner than it really is. So it forces the EFI to hold the injectors open longer, effectively richening the fuel mixture. Because we have a fairly accurate idea on how the Delphi O2 sensor works and the HD Delphi ECM operates, the XIED can precisely manipulate sensor signals to produce predictable results.
We have found that the Road Kings generally are not going to need the Stage 1 download. Occasionally I find that Ultra's like the change in the ignition advance curve the Stage 1 download offers, but they still tend to need the the extra fuel the FL-XIED-10's provide.

I run the Dynojet Power Commander V on my 12 and do not need any service department downloads to increase fuel or change timing. Beauty of the system is you simply look up a similar build and load the map and ignition table to your bike after installation. problem solved, more torque, horsepower, better fuel economy and less heat. What a deal for less than $300
The less expensive way to go is $100 for some XiED's

You do not have to do it. Your ECM will compensate for just the air cleaner...it will keep it at the EPA mandated 14.6:1 which will not damage your engine, but it is less than a satisfying riding experience.
By installing the XiED's you will get a much smoother running engine, and it will not run as hot. Surging and hesitation that is common in the stock EPA tune will be gone.
