actually there is another way of advance/retard ur timing... which in fact is the proper way compare to messing with ur distributor....
this u need adjustable campulley... advance and retard using it....
this is the basics of DVVT, VVTi, CVT, etc. works.... only that we are doing it manually while those technology advance/retards it according to ur driving style...

normal one is BP5ES.... try use BP6ES... forced induction engines usually use heatrange 7-9....
When pump v-power, the sound not reduces also..

The 'tak' sound also got related with air cond.. Because when hot, it got tak sound, rpm increase.. When cold, 'tak' then rpm drop..
Some more I thought it work like this ;
As we know air cond pull alot of power.. So when our car underpowered, then the compressor stop activate then got back power.. When got power back, then the compressor will activates back.. Will it happen like this?
