Bro's, if any of you whom have done the adjustable cam pulley mod, could you share with us which cam pulley is the best value for money and which workshop that has the right tools & expertise in helping to adjust the power band correctly? Regards.

I've read some posting in WAC Forum whereby if you shift the power band to lower rpm by advancing the timing, you will have better pick-up and thereby better FC cos' we downshift the gear faster...

The price range for a adjustable cam pulley for NA engine (ie. non-turbo) will be less than 200 to 300+ where workmanship costs will depend whether the mechanic uses high end sophisticated tool or just using plain observatory skill...

Yeap, i think performance at high rpm will be gone but for me as i'm very afraid of receiving a saman from the police for speeding, this mod would not affect me at all.....

So, Bro's do you any good competant workshop that can help me to accurately determine settings for the adustable cam pulley?
