Dumb Tuning question.

We are talking about Two 07 Charger SRt's.

Mine had a tune on it when I bought it. The other is stock.

I plan on getting a LMI and cam. My problem is My car was already trinity tuned so My trinity is basically useless to me unless I go back to a Factory tune. The trinity will not over write the other Trinity tune. The owner of the stock SRT wants a CAI and Tune.

So my question is.

Can we take my CAI and PCM and swap it with the Stock Charger allowing me to use my trinity when I get my Cam, LMI and 180* Tstat
