Queen Creek - Our Home Base
Queen Creek is home. Our shop sits at 22375 S Scotland Ct Suite 105, and it is where every dyno pull, tune, and build comes together. Being right here in the East Valley means local enthusiasts get a straight-talking performance shop close by, without hauling their car into the middle of Phoenix traffic. Stop in Monday through Friday, 8:00 to 5:30, or call us at (602) 762-4916 to talk through your project.
As an owner-run shop with decades of combined automotive and motorsport experience, we treat your car like it is one of ours. That gearhead-first approach is a big part of why local drivers keep coming back, and why we hold a 4.6 out of 5 rating across 60 Google reviews.
Serving the East Valley and Greater Phoenix
You do not have to be in Queen Creek to work with us. Enthusiasts drive in from all over the Valley because quality in-house dyno time and custom tuning are worth the trip. If you are anywhere in the East Valley or the greater Phoenix metro, we would be glad to get your car on the dyno.
Not on the list, or a little farther out? Reach out anyway. Plenty of our customers travel from across Arizona for a proper tune, and we also offer remote tuning for drivers who cannot make it into the shop.

Why Enthusiasts Make the Drive
The main reason people come to APA from across the Valley is simple: we run a Dynojet dyno in-house. That means we measure real, repeatable numbers and tune your car under load instead of guessing. Pair that with custom ECU tuning through HP Tuners, including Mopar ECU unlocking, and you get a calibration built specifically for your engine, your parts, and how you actually drive.
We also work with trusted names in the industry, including RideTech for suspension, Dynojet for dyno and tuning hardware, HP Tuners for calibration, and Texas Speed & Performance for proven parts and cam packages. Every build is different, so we quote your exact combination and walk you through the current options before any work starts.
