That is a pretty common issue with off the shelf performance tunes and california 91 octane gas. If you know the production date of your car I can make a pretty safe guess on which DME you have for the 95MY.
Turner and Dinan chips really need a better gas than 91 octane Cali gas. Can easily be adjusted for though if not using one of the 10+yo standard tunes.
