You cannot install a chip onto the ECU. Those days are over, lol!! You can flash a tune into the ECU tho. A handheld tuner with preset tunes like Diablosport Predator, SCT Xcal, and others should give a nice noticeable bump in power, harder shifts, and get rid of the nannys. A custom tune should get a bit more power especially if you're datalogging on the actual road and sending the file in to be adjusted. And a dyno tune is about the same as a custom tune but just can be done faster and is safer because you're on a dyno instead of out on the road. Either way is good. But I would hold off on a dyno tune until you get some extensive mods.
