i burn out just like you do.  My car feels like it just isnt getting a hold of anything.  It is so slow i 1 and 2 and mean as hell in 3rd and 4.  I cross at 6400 or close to it on the spray.  I think 28s would help.  If i have gear problems they would help, and put more tire on the ground too i think.
