i had these itr cams in my car for a while now and i just decided to turbo the car. my question is am i better off with the stock gsr or the itr since its already in the car. would i gain alot if i stuck the stock gsr back on or is the itr makin more hp.
 
if you have cam gears on the itrs, you can tune out some of the overlap of the itrs. if not, throw in the GSR's.
I've seen 600+ whp on gsr cams
