yeah i have also seen good power gain via ps-powersport goodies.... as for mine, im using unichip q+ and also got good result.... but all the engine build/mods needs to be done first to get substancial figures as u can see on my dyno report.... pretty much i wanted a superstreet spec that i can use for daily driving..... did all the bolt-ons job, pnp here n there, beefed up the powertrain+drivetrain+etc, and at the point of dyno until now i only use shell v-power racing + fully syntetic oil for engine/gearbox/etc.....(nak maintain lubricants a bit costly, but dont use ayam brand la) well i got the figures i wanted but even now drivability and economy decreased especially in traffic jam or lower revs...damn! but overall my car revs happily to the redline and as u can see from the graph, the car is best driven at high rev.... anything lower than 3500rpm mmg x berapa best..... muahahah kalau jln asyik jem mmg minyak kapak, clutch berat mcm nk lompat2, nk kena maintain rev......hehehe.....tapi kalau jalan clear such as highway driving...hmmmm thats where the investment paid off....cheers...
