The TPS (throttle position sensor) is different, that is just when the computer decides to put some fuel into the engine, which can be adjusted to lower revs to help with smooth slow riding...
I think you mean the TRE (timing retard emiminator) which does the same as the g pack by derestricting in gears 2 and 3. can be done a number of ways cheaper or free, just search for it, or them both for best tuning!
Northy will correct me if I'm wrong, he's the 1 in the know.
