hmm, do you mind to mention what are the famous problem? does it always require a LOT of times and MONEY ?

i also have some minor creaking noises inside the cabin. so far, no other noises.

as i have mentioned earlier, my car does have some mods. this is because i wanted to rid the car of the slight dip in low end torque. while the cps had eliminated most of the torque dip, it is still there. the mods have eliminated it and i now have much better low end acceleration all the way to the mid range BUT i have lost top end kick. so, from 150kph till top speed, it is not as punchy as before and i have lost about 10kph from my top end. so, no more 195kph runs.
