So I have been doing USGT at my local track for 2 seasons now. And have become comfortable with my car and driving ability, now how to go faster??

let me give you soMe details on my ride. First off it’s a X-ray T4 20’. Is on the alum flex chassis. It has the USGT motor and spec tires. Run hobbywing xr10 pro 120. It runs straight and I use a Sanwa MT44. My issue is it feels like it is dragging its butt around the track. My spur is 90 and running 52 tooth. So what can I do to make it run faster. Is it a setting on the transmitter. Or do I need to change settings in the ESC? If it’s the ESC is there somewhere that breaks it down in layman’s terms that I can understand how and what it impacts.
amy help from the group would be greatly appreciated.
