Does the Aftermarket Down Pipe Help with increase of power from the trax, wondering if anyone has changes there and what brands you have used.

Aftermarket downpipes do make quite a difference especially on stock turbo vehicles. The only thing is, as you will feel a difference, to get the most potential out of it it'll probably need a tune to get the ecu to work with it better.

can any one that has done an ECU Tune can you tell me what you notice from it, being a new trax I doing want to just tune unless I know what I am tuneing for

Check with guys who have done a sonic turbo or a cruze. probably similar results.
