240z73kat

Hi seeing if there are any reputable shops in San Diego that work with tuning nistune. Also diagnostic and repair. Have a 240z running a turbo ka24de. Had the car for a while since 2012 was running fine till recently. I didn’t build the setup it is currently running and do not have the time these days to go through the car myself as family and work is consuming me.

Currently now the car will go lean under WOT when going into boost. AFRs will climb. Not trying to diagnose and work on it myself as I have other priories but would like to enjoy driving my car again.

So any reputable shops that can assist me and of course further the performance future of the car would be great. Thank you all in advance.
