If only changing the exhaust (complete) on a 12 RGU but leaving the air cleaner stock is it necessary to add a tuner? what are the pros and cons to doing this? Just trying to figure out if I can add the complete exhaust and get by for a while and them purchase the AC and tuner or if I must wait and do everything at once. fyi going with Drago true duel system.
but check the Ness Big Sucker at about $120 on ebay from easternpc
This high flow intake comes with a washable oiled filter media, and offers a chrome version which complements the black/chrome motor
and many of us use nightrider.com XIEDS for tuning compensation- about $105
Tons of threads on this. I'm buying into the thoughts that if you change one or the other (Exhaust/intake) you don't really need to do anything. That being said-a tuner with or without mods will improve performance/cooling etc.

Because I am new to the forum I do not have PM capabilities as of yet. How has the XIED performed? How long have you used it and did you use a different fuel manager before. This is the first I have heard of this product but it is of obvious interest do to price and ease of installation.
I've been using the xieds for almost 2 years, and with my "stage 1" no further tuning compensation is needed.
the xieds are simply a resistor pack which plugs in between the o2 sensor and the computer.
the xieds make the computer think that the motor is running slightly leaner than it really is
...consequently the computer causes the fuel mixture to be slightly richer than it might normally be- about 6 to 8% richer.
this is enough fuel to compensate for the increased air flow into and the exhaust out of the motor.
my fuel economy dropped for 44 mpg to 43 mpg...
performance is good for the stock 96" motor on my 09.
the xieds are 'active" under most riding conditions, anytime the computer is using o2 sensor data to calibrate the fuel injection- which is 90% of the time.
bang for buck, certainly there.
plug and play
instantly removable should the bike go in to a dealer for warranty service ( you do not want to go in for a warranty problem with a modified computer)
a motor which has had further mods such as cams or headwork should have a more complex tuning solution- for a stage 1 bike xieds are a reasonable solution.
when I bought my 09 w/5000 miles in completely stock trim, it had problems with preignition under certain conditions ( 2800~3200 rpms up a 6% grade)- installing the xieds fixed that and allowed me to in stages change to hi flow performance mufflers ( supertrapp supermegs) and after evaluation install a ness big sucker- all to good result.
I have tuned bikes and cars for years and have some ASE training
You don't NEED a tuner. But i would definitely do something about the very lean condition on ANY bike I own. Even a stock bike. Look at XIED's over at nightrider.com. Lots of good info there.
Personally, I wouldn't waste money on tuner unless you're going to do cams and/or headwork. Xied's work great on stock and stage 1 bikes.
Either way, richen up the mixture. Your bike will run cooler, and be happier.
Had the Xieds on my old bike..(07 with 103/255s, street legal SE dealer download). they worked fine if you are just looking to fatten up the mixture a touch and help cool it a little. If you are looking to get the last available spec of hp out of it.. get a tuner.

If you're lookin' for the "last available spec of hp", you'd better be lookin' at compression bump, cams, heads. At that point, yeah, you'll need a tuner.
