Who here is running a twin throttle body whipple and making 17 psi or more? Just got off the phone with whipple, talked to a guy named Art i think, he said he was the owner of the company and was taking tech calls because mike was on vacation. He said that i can't make more than 14-15 psi with the stock throttle body, its just to restrictive to flow that much air. This is my first whipple but i thought that was a complete lie. Whipple owners with twin tb's please chime in with your pulley combo and boost pressure.
