Also, I did contact ess for a 15 or 16 psi pulley. I did get a paypal invoice from them but they did not specify which pulley it was for. I was concerned about just throwing it on because with the larger TB drawing more air, from a common sense point, I figured would multiply more air through the SC raising the manifold pressure (seeing 13 psi on an 11 psi pulley). This same concept is what I was leaning on to see 400rwhp on the 11 psi pulley. I might change out the pulley before the tune. Hopefully it won't raise the manifold pressure above 20 psi...
