APA Custom Shop is a performance and tuning shop at 22375 S Scotland Ct Suite 105 in Queen Creek, Arizona, open Monday through Friday. We run an in-house Dynojet dyno, so East Valley enthusiasts get measured, data-driven results on everything from a first dyno tune to a full build.
Built for Queen Creek drivers
Queen Creek and the San Tan Valley are full of trucks that tow, muscle cars that see the street and the strip, and daily drivers that deserve to run their best. Our in-house Dynojet dyno lets us tune for the heat, the elevation, and exactly how you drive, not a generic file from somewhere else.
- In-house Dynojet dyno tuning with HP Tuners
- Cam packages, long-tube headers, and exhaust
- Supercharger and turbo installs
- Engine builds, swaps, and custom fabrication
- Performance diagnostics and honest recommendations
