firstly the gtech doesnt actually start untill you do ie you can actually creep forward (its good like that) well wen i got it i knew something was up as id previously owned a glanza which was alot quicker. i first tried fault finding and i went to a place for fault diagnostics and they cudnt seem to find anything, nevertheless i got it dynoed and it was running at 130bhp and that was witha catback exhaust and induction kit and no boost restriction. i timed the 0-60 and it was shite cudnt get it under 7.0 and was normally in the 8's. was always struggling for traction with semibald tyres. anyway bought new plugs new leads dizzy cap rotor arm, new tyres and it started feeling right again. 0-60 was then down to about 7flat and i felt happy again..started modding a little more and the better it got, on 0.8bar boost best 0-60 i got was 6.4 with no back seats on my own. and a few lil mods. was happy with that.
