I didn't do inlets separate so it's tough to gauge the gain from those in particular but I can say with certainty my old tired turbos picked up good power from them. My car went from 410/440 to 462/530 with just the addition of down pipes and inlets and no tuning changes, to 480/550 after minor revisions along with significant drop in wgdc. We all know how big down pipes are on these cars, but they don't pick up near that power on their own. My turbos have 104k on them and have zero issue consistently hitting peak boost of 23lbs and hitting my target curve.
