I have the same year and highly recommend an ECU flash. I got mine flashed by Guhl Motors back when they were still flashing sport bikes, however there are many companies you can go with. A flash will remove gear based ignition timing and speed restrictions, customized MAP, TPS fuel and ignition mapping based on mods, my flash raised my rev limiter by 500 rpm, lowered my fan set temp to 180°F. A fuel module like PC5 is good to fine tune fueling, but that’s all it can do. Getting my bike flashed really woke it up. Now it pulls just as hard from 150-185 mph (yes I do have a GPS calibrated speedo healer) as it does from 30-100mph. Before I got the flash I had 15/44 final gearing which helped, but with the flash I found it completely unnecessary so I went back to 16/42. These USA trim fireblades are extremely restricted from the factory which is why they get such a bad rap as being the weakest liter bike. Ever since my flash though I can hang with even newer bikes that should eat me on paper. Other mods that helped add to the bikes rawness were BMC race filters and Venturi systems velocity stacks. Even better would be Sprint P08 dry polyester air filters. Just look at the new fireblade RR-R sp. The US trim is so restricted you can get 42 horsepower gains with a stage 2 BrenTune and BTM velocity stacks. Moral of the story, if you want all you can get out of this bike, you need an ECU flash. Power commanders are great but they can’t accomplish anywhere near all the stuff a flash can.
