    98 vmax seems to dog after 5krpm

    My vmax seems to be staving for fuel after 5k more so in higher gears then 1-2. I dont know if the v-boost just isnt opening or what but it does seem like it randomly will come alive for a second if i keep the hammer down but its acting like a dirty fuel filter. what can i check? Plugs...
