Ive got a heat rapped janspeed 4.2.1.
Bob on it is...
4-2-1 = give more torque across 2.5k - 6k
4-1 = top end speed increases i think...

I had a 4-1 and tbh car felt faster without it
4-2-1 is the way to go really

I think he did........
4-2-1 if your car is low
4-1 if you car is low then you'll flatten the bottom of it
Thats about it
