Suzuki TRE Differences
Below are shown Suzuki TRE Differences can make to a Suzuki GSX-S1000. Removal of speed limit in 6th gear by STP (secondary throttle plates) and more responsive throttle in the first 3 gears as the ignition is more retarded in the lower gears below 30% throttle. All these advantages and many more can be done with a re-flash
No difference in full WOT Power, so a TRE will not give you more power, just a more responsive throttle at low speed and a slightly higher top speed.
So if you are flashing your GXS-S1000 then it is a waste to fit a TRE but it can improve your bike if you are not flashing it.
