When i installed a S1X cam in my car i was told by the people from Intense to raise my shift point to 6300 rpm. So i sent my pcm in to DHP and had them do so. Now the car will run up to 6100 or so rpm and lay on its face till it shifts. When i first had the cam installed i was running 13.6 but prior to the cam install i was running 13.7 with 1.9 rocker arms. Now with the shift points raised i'm only running 14.4 to 14.0. I thought the car would run much better with this cam but i just haven't seen it yet. I have Intense push rods, comp cams lifters,105 springs and retainers, new timing chain with tensioner. Does any else with this cam run it up to 6300 with out problems?
