Is there a way i can increase acceleration without any power modifications, like doing something to the throttle body or umm I dunno

Grippy tyres.

If there is a dead spot at the beginning of the throttle travel, get the cable looked at, but the 6G engine is renowned for its urgent throttle response at all times. So if it is fine and you go to adjust it, then you would probably just sit there spinning wheels and wasting fuel. Look into grip options
