Late-model GM performance builds and Toyota Prius hybrid repair define the dual specialty at SmarTech Auto, operating from Suite 201B at 7633 El Cajon Boulevard in La Mesa. The shop completed the first American installation of the Harrop 2650 supercharger system and continues to handle cam swaps, engine builds, and forced-induction tuning on LS- and LT-platform vehicles, with used Prius sourcing available through hybrid-stocking dealers like EpikSun Motors on the same boulevard. On the hybrid side, SmarTech reconditions Prius battery packs, replaces blacked-out combination meters on second-generation models, and performs head-gasket repairs on Lexus CT200h and other Toyota hybrid platforms. The owner holds a Cal Poly Pomona engineering degree, applying oscilloscope-level electrical diagnostics and manufacturer-specific scan protocols to both high-horsepower GM builds and high-efficiency hybrid drivetrains. Routine maintenance like oil changes and filter service is directed to quick-service providers like Valvoline Instant Oil Change, freeing SmarTech's bays for complex performance and hybrid work. Most demanding builds involve LS-series engine swaps with custom wiring-harness integration, requiring ECU reflash, transmission controller calibration, and chassis-dyno tuning to verify horsepower and air-fuel targets under load.
