Good Seneca Shop in SoCAL or Phoenix?

[MD500_Pilot]

I have had fantastic experiences with my mechanic over the years, but their shop is doing more and more avionics and less and less repairs and pretty much everytime I put my plane in the shop it takes weeks and weeks to get it back due to their backlog, so I am looking for a new mechanic geared less to avionics for my Seneca either in San Diego area or the Phoenix area.

I commute between KCRQ (Carlsbad, CA) and KDVT (North Phoenix Area) every week, so I could use a good shop in either of those local areas.

I am having issues with my MPs and RPMs with split throttle and one engine rapidly accelerating/decelerating over the other engine with same throttle movement (factory remans with ~400 hours) and I could really use a fantastic Contentinential shop that understands these engines. I have spent thousands and the problem still exists.

To finally solve that problem once-and-for-all I would be happy to travel, but I still need a day-to-day shop for minor repairs, annuals, etc.

Any help would be greatly appreciated.

Thanks
