I was looking into buying these mods and wanna know what numbers they gained and if you notice the performance before I jump in buy them. Only mods I have on my engine atm is a steeda CAI and tune

 

Skip the throttle body. The Boss Intake needs to be spun to 7600-7700 to reap the benefits. Are you willing to do that?

 

Not really. With a good tune the Boss IM starts showing gains above 5k rpm and doesn't start losing power until after 7500rpm. If you're not spinning the motor fast enough for the Boss IM to make a difference, you're not trying hard enough.

The fastest N/A cars are running either the Boss or Cobra Jet IM.

 

Where did Zack say he was trying to a record? And no not all the fastest cars that are N/A run the Boss Intake. In fact the fastest auto to date runs the stock intake.
