    Are you using the stock 87mm nozzle, the 83mm nozzle, or adjustable nozzle/rings?

    It would help if you posted the year also! As tommygunner said, a complete list of mods is required to answer your question more accurately.

    OEM nozzle on a 2010 TX was 87, all others it is 83mm, rings?. So as you can see you need to be more specific.
