Dyno tuning, turbo builds, suspension, brakes and exhaust for the car you love to drive — measured before and after, explained in plain English, and smog-legal in California.
The eight upgrades — hover, tap or tab through all eight
Upgrade 01 · The tune
ECU calibration on our dyno
Fuel, timing and boost mapped for your car, your fuel and your parts, one pull at a time on our in-house chassis dyno. You leave with the before-and-after sheet.
Upgrade 02 · Intake
Cold-air intake
More air, cooler air, less restriction. On its own it is a few horsepower and a better sound; with a tune, it is how the rest of the build breathes.
Upgrade 03 · Boost
Turbo & supercharger
Hybrid and larger turbos, supercharger kits and the fuel system to feed them — sized for the power you will actually use, not a number on a forum.
Upgrade 04 · Intercooler
Front-mount intercooler
Keeps intake temperatures down pull after pull, so the power you made on the dyno is still there on the third lap or the fourth on-ramp.
Upgrade 05 · Exhaust
Cat-back & downpipes
Mandrel-bent stainless, tuned for a sound you can live with on the freeway — and only parts with a CARB Executive Order on a California car.
Upgrade 06 · Suspension
Coilovers & alignment
Ride height, damping, corner balance and a performance alignment, set up for how you drive: commuting, canyon roads or a weekend at the track.
Upgrade 07 · Brakes
Big brakes, pads & fluid
More power means more speed to shed. Multi-piston calipers, two-piece rotors, track pads and high-temperature fluid, bled and bedded in before you leave.
Upgrade 08 · Wheels & tires
Wheels, tires & fitment
Lighter wheels, stickier rubber and the right offset — mounted, road-force balanced and checked for rub at full lock and full bump.
A baseline pull before anything changes — and another after
Every build starts with a baseline pull and a health check — compression, boost leaks, fuel trims — because power added to a tired engine is a breakdown waiting to happen. We tell you what your car needs first, and what it doesn’t need at all.

Dyno tuning
Custom calibration · baseline & final pulls · one day
Every tune starts with a health check and a baseline pull, and ends with a printed sheet that shows exactly what changed. Pump 91, E85 flex fuel or race gas — mapped for the fuel you will actually buy.

Dyno time books up about two weeks out. Maintenance, brakes and alignments usually get a bay the same week — and we look after stock cars too, with the same care as the builds.
The team
Tuners who drive what they build.
Andre Whitfield
Head tuner · ASE Master Technician · best pull 1,046 whp
Fifteen years on the dyno, from rotaries to twin-turbo V8s. Tunes for the car you drive every day first and the number second, and will not flash a map he would not run in his own car.
Luis Ochoa
Chassis & suspension · ASE A4 · best lap 1:58.4
Races a Miata on weekends and sets up coilovers like a race engineer during the week. Corner-balances every car he touches, and will talk you out of springs that are too stiff for the street.
Sam Reyes
Engine builder · ASE A1 & L1 · best pull 682 whp
Builds the engines that make the big numbers survive: bearings, rods, oiling and cooling, measured twice and logged. Will show you the clearances on paper before he shows you the dyno sheet.

Friday dyno day — two hoods up, one loud afternoon
My STI made 312 at the wheels on E30 and it still idles like stock. Andre walked me through every pull and sent me home with the sheets.
They talked me out of the expensive coilovers I came in for, set up the ones I had properly, and the car is a different animal. Who does that?
Passed smog with the intake and full exhaust, because every part they fitted had the paperwork. That alone was worth the drive from Roseville.
Rod bearings on an M3 is a scary invoice. Written estimate, photos of the old shells, done when they said, two-year warranty. Zero drama.
Prices in US dollars before tax. Every quote is written and approved before we order a part, and every repair and install carries our 24-month / 24,000-mile parts and labor warranty.
Questions
What people ask before they book
01Will a tune void my warranty?
It can. A manufacturer can deny a claim on a part your tune affected. We tell you plainly what is at risk on your car before we start, and we can flash it back to stock before a dealer visit.
02Is it smog-legal in California?
We only install emissions-related parts that carry a CARB Executive Order for your car, and our tunes keep every monitor working. Your car passes smog, or we make it right.
03Do you work on stock cars?
All the time. Oil changes, brakes, alignments and diagnostics on everyday cars are half our week, done with the same care as the builds.
04How long does a tune take?
A Stage 1 dyno tune is usually one day: drop off in the morning, pick up in the afternoon with your sheets. Bigger builds get a written timeline before we start.
05Can I watch my car on the dyno?
Yes. There is a window into the dyno cell and a couch beside it. Bring ear protection or borrow ours.
