Lost a little boost after fitting turbo back exhaust

    I had my Pipewerx Dwonpipe, decat, and my miltek cat back fitted today.

    I haven't yet had the stage 2 map, planning on a trip to Rtech soon though.

    The boost seems a bit hesitant at the top end now. In fourth/fifth gear pointed up hill with WOT it used to peak at around 24psi, then drop to 22 and hold for a bit before it started to drop off in higher revs.

    It now peaks at 21/22 psi, flutters about a bit and drops off quicker than it used to.

    Is this just because I need my MAP to match the new down pipe / system ?
    or as i suspect could it be a weak turbo which has been pushed a bit harder due to the pipe and is dieing ?
    Or something else ?

    You may want to reset the ecu/throttle body has the characteristics have changed and it will need to learn its new lungs....
