Camshaft upgrade ?
#4
The comp cams arrangement hasn't proven itself to be worth the work. It's not much better than the stocker, minimal performance gains. I would check out ZZ Performance (click on grand prix, same engine), something like their gt1 cam. It is a nice basic cam, not to lopey, won't throw codes, etc.
