I found this through someones elses post.... but is the proflow tb mod worth the $155 ? (www.proflowdesigns.com) will i really have a noticeable difference ?

 

It is known to increase horsepower on FI cars. On the stock engine no difference is seen. Great mod for superchargers.

 

I just got one I will let you know. But I hear it is only worth it if you have a SC or turbo.

 

Thanks for the help guys... im trying to stay away from the FI route.

 

Even on a NA car it makes a notable difference in throttle response (larger orifice, same linkage) but since it is not believed that the TB is a constraint on a NA engine it makes sense that it will not add power. BUT I have not seen a before and after dyno test, and like mine on my NA car.
