Galpin Auto Sports installed my air intake, exhaust and valve controller. Jaime was my P.O.C. there. You will be paying dealer shop rates but you also get the satisfaction of them knowing how to work on these cars. You can take your car for a service and ask Jaime to bring the car over to GAS. That way, you will have the loaner from Galpin service dept and kill two birds...
I would also highly recommend R2 Motorsports in Castaic. Contact/owner is Raffi. They work on several of the Emira owners on this forum. They installed my short shift kit, spacers, and lowering kit. Raffi is a fellow car enthusiast and just looking at his service bay, you will be treated to a myriad of super/hyper cars being serviced.
