dinmsab: hahaha...intersted ur words..If you want speed/torque/HP, you are going to lose something in return (usually its fuel economy). I do not believe that this product may increase the 20hp and reduce fuel consumption. if that, do I need a major modfikasi to get 20hp.??

just my opinion...tq
Lets face it, 20HP increase is indeed a lot. This is not gran turismo where changing a few things can get you far; sorry, this is real life. I have buddies who go crazy with their neo, changing the exhaust, using open pod filter, use ECU piggyback and when they dyno they barely touch 15hp increase.

This thread is a good example on how a cps owner who upgrades her neo as if she was printing money, when dyno she barely got 123WHP, for comparison a stock neo WHP is about 110-115(i'm being optimistic here). That's barely 13HP upgrade for a crazy ass modification!
R3 also offers an upgrade package for the CPS, for 10k you can get a whopping 15hp and 15nm.

So sir, my point is as follows: It is indeed possible to gain a strong 20hp for your neo, and yes you will need some wallet breaking modification if you modify the car the "NA" way. If your so crazy for power and are willing to sacrifice anything then just opt for bolt on turbo NA. Around 10k will get you all the HP those small neo tyres can handle.
In the end, it all boils down to what your policy is; To me my car is not only for enjoyment but also is an investment, it's my drive to work daily while at the same times provides me with amusement. As such i'm not willing to sacrifice car life span and fuel consumption for a teeny bit of HP (although this doesn't mean I don't rev my engine hard sometimes). ;) VROOM VROOOOOOOOOOM
