No, i smoothed the interior ridges and on the rear of the LS6tb its reduced for an odd reason. I have a DBW tb on my vehicle so messing with the blade even a simple butterfly grind on it is more often then not found to cause idle issues. If i had a cable drive system i would of gone more port with a new blade and more mods on it. In this car it was a mild port job though but worth it.when you ported your throttle body, did you use a bigger throttle plate?
