I installed the base trifecta tune on my otherwise stock 2014 LTZ last January. Happy with it except the low speed drivebility is terrible.
Biggest complaint is while driving in the 35-40 mph range and someone in front slows down to turn. Let off the gas to slow down and roll into the throttle to accelerate, the car is very unpredicatble. Sometimes it doesn't react to the throttle as it should, other times it over reacts, a violent unnecessary downshift.
Thought this might be related to the hesitation problems so I've experimented with different plugs suggested here. Currently have the -8 NGK iridiums. But that doesn't seem to help any.
Any other trifecta tunes with similar experiences?
