A possible solution
two i-pods each with ( bose ) over the ear headphones .
when you come to a steep hill ( Eisenhower Tunnel , Asheville eastbound , grapevine , dunsmuir , and so forth ) get out the ipods for you and the missus .
Play your favorite tunes .
Get in the RIGHT hand lane .
Spin that V-10 at about 3 /4 throttle and climb at 40 - 45 .
The music will calm your urge to go .
The headphones will cancel the extra engine noise .
OR get back into diesel power .
p.s. my 2002 duramax , bought new , has been trouble free .
and i would have no problem with a cummins or powerstroke as a TV .
