Question After market mods for 2012 dmax

What are everybody's opinion on doing a complete delete and tuner in the new 2012 lml? I am very close in doing it however I don't want to void my warranty and have something go wrong.

If you haven't heard the EPA confronted H&S over their tuning products. They have since stopped production/shipment of the XRT Pro and Mini Maxx. There are some vendors who still have product available. If you are considering doing an exhaust and tuner, even if it is later, you should consider purchasing now while the software is still available. Not sure what will come of it in the future.

If I can be of assistance, don't hesitate to ask.

Take care,
