to check whether they did a "download" rev the motor- the stock rev limit is usually 5600 RPM's.

if yours revs higher, you know that a download has been done.
and you'll probably be fine

I have been using a Daytona Twin Tech tuner cost about $250.00 three years ago, good product but wish I had the bread to buy a self tuning model.

You can adjust the one I have on the fly but you need to have the chart to make adjustments as needed. You need a tach on the bike so you can identify the range you want to tweak. With the cost and finding a good dyno tech you can easily exceed the cost of a self tuning unit.

If I were a rich man...

 

With the slip-ons and air cleaner you probably should have.

 

I have a 103 did the de-cat with Slip-Ons and just felt it would run cooler and better with a tuner . I have a Power Vision and did a map from Fuel Moto no auto tunes yet but I can see it coming . It did cut my mileage about 3 mpg I was getting 50 or 52mpg so it did what I needed it to do add gas . The bike runs well and a bunch cooler .

 

the guy I bought it from said he bought it new and had the stage one a/c and slip ons put on at the dealership before he picked it up. I am assuming they did it when bought. he said he wasn't sure but they did charge him for the installation and something else.

Yes you should get a tuner, as another poster said with the slip ons and upgraded air cleaner it may of been a good ideal to of had one then. Now there is a chance the dealer did a flash but a tuner would make it run a lot better. Now that you want to add the Cobras you should definitely get some kind of tuner. Riders choice.


I started my Cobra Power Port install today, I chose to go with the Fp3, budget friendly for me and I probably will not do more then a stage 1 anyways. But anyways good luck to you.

 

Real curious as to what this does for cornering clearance. Keep us posted..
