The average here gained 5.3 horsepower! and 1.9 ft/lbs torque. Check out the Dynojet Race Routine between the stock vehicle, the stock throttle body and the TPIS throttle body air foil.


Subjective:

I picked up this used TPIS air foil for under $30, and you can see what it gave me. Not much. But then again, at $15 per hp, its not that bad. 2hp is just not enough to feel on the street. I wonder how much this would help once I get the supercharger on?
