Hey, first post on here. I am the proud owner if a 2005 GSXR 750. Just bought the bike, have been riding my whole life but this is my first sport bike or street bike all together. At 40 I wish I would have got one sooner. Posting on the tech forum to get some info on the Power commander 4 I have coming in the mail. I am curious as to what accessories I should get for it such as fuel tuner or ignition tuner? Am I fine with just the Power Commander itself? The bike is stock aside from the Yoshimura full exhaust and BMC filter also in the mail. Any advice on tuning the bike or advise on the bike in general would be much appreciated. I am not going to track the bike, planning on street for now.

If you want your tuner to have more options for making power, you can get the ignition module. Otherwise, you don't really need it.

And there are significantly better options than the Dynojet quick shifter.

It should be pointed out that the PC is to fix a fuel mixture problem. If the bike is fueling fine with the stock mapping, a PC will not gain you anything.

The only way to really see if you need it is a dyno run. My K6 750 track bike is stock except for a Yoshi slip on and it fueled just fine with the stock mapping. I did an a Bazzaz unit but that was to get the quick shifter.

Thanks for the info! I'm downloading a tune this morning and installing the Power Commander. Man, you can plug more into that thing than I will ever need...fuelel module, secondary fuel module, auto tune. I'm not building an Iron Man suit LOL. The auto tune sounds like a good thing but I'm not welding in an 02 sensor. I made a mstake in my first post, it only has a Yoshimura bolt on silencer, not the full TRS. I believe that setup uses springs to hold the silencer on. I will be getting that after I do some research on the other exhaust systems available to make sure I'm getting what I want. Yesterday I was riding with my son on back and the bike was going up to 220/221° at red lights in traffic. I know that's normal on hot days but it was only about 65 or 70 degrees out. Seemed like the bike was running a little lean. It hits 180 in no time on cool days. I still have to put new plugs and an air filter on, the stock one in it is definitely DOA. Bike has 17,000 miles but it looks like it just came off the showroom floor. I'm the second owner. I love the way these bikes are built, GSXR will be my next bike as well.

Kind of surprised no one suggested to leave the bike as is and get a bit more comfortable on it before you start sucking more power out of it.
I understand you've been riding your whole life, but this is your first sport bike so it's a different style of riding from whatever you're used to. Granted - the PC and any accessories you add to it won't net you tons of power, but if it was me - I'd be putting my dollars into suspension/braking first but that would be after I got more comfortable on the bike as it sits.
I'd also check to see if the stock suspension needs to be refreshed.
The K4/K5 tokiko brake calipers tend to need regular servicing, flush out the brake lines/reservoir for any condensation, swap to SS lines perhaps, etc.

I bought my K4 with a PC on it, uploaded their canned maps for the modifications my bike has, and noticed almost no change. If I didn't have the PC, I probably wouldn't buy it. If the Bazzaz was available for my bike I'd go that direction like someone mentioned above. They offer a bunch of add-ons - quick shift, traction control, auto tuning, etc.
