    Default Twin Turbo Tuning

    Just trying to slowly learn more and more about tuning.

    As for tuning for twin turbo's I would assume to increase boost pressure faster then then on a single? I would also believe I would need to lower PW to achieve same power output due to increased air going into the engine?

    Thanks for the help gentlemen.

    Never hear anything on this? When you say twin tuning are you running two fixed vane turbo? If so, there's not much you can do to control the boost as it depends on the duration and timing...one thing I do is disable the underboost and overboost codes..I think around P0234 is where they are...and disable anything pertaining to variable vane turbo...that's just what I have done and had good luck with.

    I suggest not disabling under boost codes. The reason they code are legit. ....match up desired vs actual and you will not get a under boost code. The under boost can also put the Ecu into a limp home mode in which with the code off would be hard to diagnose.

    Gotta pay to play, make one change at a time, do a little searching then ask your question. The only stupid question is the one not asked...
