'06 CCSB FX4 6.0 Stock. How much power should I have over 70 mph? I've only had this truck a couple of weeks and haven't got gauges yet. Planning on the Edge soon. Stock boost gauge seems to go up around 25psi, but on the highway I barely seem to have enough power to gain speed much less really get up and go to pass someone and this is empty. Can't imagine having any with any amount of weight behind me. Is this normal for a stocker or should I be looking for one of the aforementioned problems the 6.0's seem to come up with.
