With the Unichip, I know it's just a bonus if it improves your fuel efficiency. With the IHE, possible din yata. Depends still though, on the quality of the Intake ( if ever the TS will go Simota ... :doh: )

But with additional power, can you really fight the urge to push it hard when opportunity allows? Your guess is as good as mine.

:btw: if the ts would go for the stage 1 mods, id suggest him to skip the ' exhaust ' part. it's more fun to hear the intake doing it's glorious sound than hearing your exhaust roar at .... 40kph. Wahaha. ( -- again depends on the quality of the exhaust if ever the ts will go the generic way )
