LT8s
3sgte
540cc

internal all stock

does this related to any vacuum leak ?/ mechanical issues / setting in microtech or related to miss firing ? spark plug / cable plug ?

I do not have issues on high rpm / 1500 rpm and above.

Thanks for your advice.

Check your plugs, wires, and distributor. Also make sure you have the correct engine management settings for your 540cc intectors. Check around your throttle body for leaks which includes vacum lines, and gaskets. Then finally the other only reason is your injectors or fuel pump.
