Wife just got a new Colorado 2.8L and I'm looking for advice on deleting DEF and tips/lessons learned. Any advice would be appreciated!!

If you are looking to keep the emissions equipment, but shut off the EGR and DEF system. You can look at the GDE hot tune. If you are deleting they have an Off Road Tune. The engine and transmission tune together make a huge difference in throttle lag at take off and fuel mileage. Look in the mileage tread. I just posted my best mileage last weekend.

Thanks for the info..I plan on deleting ALL the emission equipment eventually but would like to get a tune that would give more pep for the time being. I will look into the GDE tune.
