The ECU for the Speed Triple and the Sprint ST are different from the Tiger; however, "current" as in electrical current is not an issue. The difference in this area is mapping for the EFI system.
In order to get somewhere near the HP of the Speed Triple, one needs to install a more open exhaust silencer, remove the airbox restriction (called a snorkel by some), replace the filter with a K&N, and get the mapping of the ECU set up for maximum HP. This last part may require one take it to a tuner that uses a dyno and the purchase of a TuneBoy key to access the ECU.
Even with all this, your gearing will probably be different from the Speed Triple unless you change sprockets to be the same tooth count as the S3.
