Re: throttle body on a ba boss 260
helix spacers are a waste of time and money. They may increase the power slightly, but overall not worth it for the price
Get the car tuned. With the engine tuned you wont need to change the throttle body.
My xr8 has made 244rwkw with full exhaust, underdrives and air filter. Using the standard throttle body and induction. Alot of forced induction Boss engines still run the standard throttle body.
