I just reached out to Extrude Hone AFM located in Paramount, CA to get a quote on my Trick Flow Twisted Wedge upper and lower intake. $750. That seems like a lot of money to get another 100 CFM out of an already good flowing intake. I suspect the horsepower gain is maybe 20? On a stock SBF 302 will the extrude hone process disrupt the balance engineered into the packaged HCI? I realize a tune will likely be required, but I don't want to spend the money only to have the car fall flat on its face below 3000 rpm.
