Performance upgrade shops in or near San Diego

Anyone in So Cal have experience with performance upgrades for the 2016 GTs (or GTs) in general.?
Potential reliability and dealer issue opinions are also welcomed. I know that there have been discussions of this type here and I've read those, just looking for some advice beyond the generic.
Am coming up on warranty expiration and thinking about some ECU or other upgrades.

thanks,

sanjeev

An easy performance upgrade is a HHT (handheld tuner) for the ECU. There are several providers here. I opted for the Renntech HHT for my 2016 GTS, though it seems the Renntech is probably the most expensive offering. It does wake up the beast. The ECU upgrade process is rather simple: insert your key in the glovebox and turn on the ignition; insert the HHT into the OBD2 port and wait a couple of minutes for the light on the HHT to change from red to green. Switching back to stock is the same process, toggling the HHT switch from tune to stock. If your battery is not fully charged, it is a good idea to keep a battery conditioner/charger like CTEK (for lithium) or the Mercedes branded CTEK installed. If the battery is low, the ECU tune update will probably be okay, but you'll get an error message on the dash. Using the lithium battery charger will clear the message.

The HHT upgrade is easy to swap back and forth. I'm leery of other upgrades as being in CA---things can be stricter than other states. Hope to leave CA soon...

LOL. I did and it’s inconclusive regarding SoCal. Lots of stuff up in Irvine or LA and as far as SFBay to AZ/TX. Just don’t want to have to drive that far in case stuff happens. Also don’t want issues with warranty or irreversibility. I’ve had issues with other German manufacturers that I had to escalate to the FTC - just takes a crapload of time.

See there are great answers and you don’t necessarily have to exhaustively read. Thanks 5thgear. Will do

I've spoken with Neema a couple of times for lowering the car and tune up when they used to be close to my work in sorrento valley. Now they have moved far but I am thinking of getting the secondary cats and lowering kit from them.
