Vince didn't originally have the no lift shift feature in his tunes, but did start including them on request. The base tune can be anything you happen to have and that you default to when his tune is switched off - it doesn't matter to him, although IIRC he would need to know which sensors you had.
Not sure why you ever turn your Trifecta tune off. By all accounts you slightly improve fuel mileage when using it and there is no benefit in terms of fuel or durability in not simply using the Trifecta tune all the time.
I turn my Trifecta tune off when I daily drive because it's activated by the Traction Control. So, to use the tune, I have to put it in at least Competitive Mode (or ESC off). In competitive mode, with street tires, I can spin the tires through 1st, and 2nd, and squeal them into 3rd. If it rains, I have a hard time keeping the rear end behind the front tires.
I'm not concerned about fuel economy... I'm running some sort of gas/E85 mix already, so I've given up fuel mileage right there. I just don't feel it's smart to have the level of power I have under the tune on the street with street tires. I can enjoy the car with the GMPP tune on the street just fine. To each their own... no judgement from me.
