turbo gsr high rpm sputter
okay so at like 6k rpm it starts to sputter and puffs of black smoke and some times a flame comes out the tail pipe. i have replace the spark plugs, wires, roter, fuel filter, and still no change, could my timeing be off? what could this be??

Re: turbo gsr high rpm sputter
sounds like the spark blowing out-
you should be running colder plugs
and reduce the gap to the factory minimum, or find plugs that are properly pre-gapped
Denso makes nice iridium plugs with gaps on the smaller side

You need a tune or either re-tune, because it's breaking up.
