Dyno tuning, ECU calibration, turbo and engine builds for JDM and European cars — done right the first time, and tuned to live on 91 octane in LA heat.
// Disowned by the V8 crowd. Fine by us. The import scene built its own standards — I build cars to them.
Anyone can post a peak horsepower figure. The question I actually care about is whether your car makes that number on the third pull, on 91 octane, with the intake air already heat-soaked from sitting in traffic on the 10. That's the difference between a screenshot and a tune you can drive.
I tune on a loaded dyno so I can hold the engine at real road load and watch air-fuel, timing and knock through the whole rev range — not just chase a peak on a free-spinning drum. Every pull is datalogged, and I read the logs, not the marketing. If your car came in on a canned flash that's leaving power on the table or running it somewhere it shouldn't, the dyno finds it in the first hour.
That's the whole shop philosophy: loaded-dyno tuning backed by data, custom ECU calibration instead of off-the-shelf maps, and the honesty to tell you when your build doesn't need the expensive answer.
The engine codes below aren't a parts catalog — they're the platforms I tune weekly and know cold, from the failure points to the honest power ceiling on stock internals. If your motor is on this band, I've been inside its logs before.
Everything a real tuner shop does under one roof, grouped the way a build actually comes together — tuning, forced induction, engine, breathing, chassis, drivetrain and fabrication. Each one is its own deep write-up with real LA pricing.
Custom calibration, not a canned flash. Whether your car wants an off-the-shelf map, a full custom reflash or a standalone ECU, I'll tell you which one your goals actually justify — and when a generic flash is about to cost you a motor. Stage 1 through 3, E85 and flex-fuel, with fuel and knock control dialed for California's 91-octane reality, written to your exact combination and verified on the dyno.
Explore ECU tuning in Los Angeles →The flagship service, and the reason most people find this shop. I tune on a loaded dyno so I can hold your engine at real road load and watch air-fuel, timing and knock through the whole rev range, then verify with heat-soaked back-to-back pulls so the number still holds after you've sat in traffic on the 10. Every pull is logged, and I read the logs, not the marketing — loaded-dyno tuning, e-tunes and datalog revisions on 91 or E85.
Explore dyno tuning in Los Angeles →Haltech and MoTeC standalone installs and wiring for swaps and big-power builds that outgrow the factory ECU. When a flash can't get you there, I build the harness and calibration from the ground up — because half-measures on the wiring are what strand you on the 405 at midnight.
A turbo is a system, not a part. If the fuel, cooling and tune don't match the turbo, you didn't buy power — you bought a grenade with a warranty void. I size the turbo to your real goal, then build the fueling, charge cooling and calibration around it so the whole package lives. Bolt-on hybrids to big single-turbo builds, on EJ, K, 2JZ, N54 and EA888.
Explore turbo kits and upgrades →Instant, linear boost with no lag — the most bulletproof adder when it's picked and tuned right.
Beat heat soak — the LA tax on boost. A real FMIC is why your third pull matches your first.
A swap done right is seamless; done cheap, it's a permanent project. K-swaps, 2JZ, SR and LS — I build the swap that actually fits your goal and your budget, wiring and all. And in California, legality is part of doing it right, not an afterthought — I'll tell you up front what keeps it street-legal and what doesn't.
Explore engine swaps →Forged internals and built motors — but only after I tell you your stock block's honest ceiling.
Injectors, pumps and flex-fuel done for real — with a straight answer on E85 station availability here.
Flow that stays smog-legal. In California the smart exhaust question isn't how loud — it's what keeps you legal and still flows, and I'll steer you straight even when it costs me the sale. Downpipes, catbacks and turbo-backs sized to the build.
Explore exhaust and downpipes →Half the intakes sold do nothing without a tune. I fit induction the dyno actually rewards — and I'll tell you when yours is already fine and doesn't need touching. Proper filtration and heat isolation, not just a louder noise.
Explore intake and induction →Coilovers are 20% parts and 80% setup. Bolting them on and skipping the corner-balance is paying for a tool and never sharpening it. I install, corner-balance and align to how you actually drive the car — canyon, track or street — so it's planted instead of just lower. KW, Öhlins, Fortune Auto and the platforms in between.
Explore coilovers and suspension setup →Power is nothing without brakes to match. On Angeles Crest, fade is what puts people over the edge.
Offset and tire choice change how a car looks and drives more than most bolt-ons. Fitment done intentionally.
The clutch is the first thing to quit when the tune lands. I size it for where the build is going, not where it is today, and sort the rest of the driveline — flywheel, axles, differential — so the power actually reaches the ground. Street-friendly to full-race, matched to your torque and your traffic.
Explore clutch and drivetrain work →A widebody is only as good as the install. Bad gaps and panel fit turn a hero build into a parking-lot cautionary tale — I fit them clean, with real bodywork, not double-sided tape. Functional aero and fitment that reads as intentional.
Explore widebody and aero →A cage is the one thing on your car you hope never gets tested. That's exactly why I won't cut a corner on one. Roll bars, harness bars and full cages built to the sanctioning body your discipline answers to — verified against current rules.
Explore roll cage and safety fabrication →Deep, platform-specific pages — engine codes, generation splits, known failure points and the honest power ceiling for each. Internal rivalry between them; total solidarity against the V8 world. Pick your side:
The most swap-friendly power in the game. Turbo it or swap it — either way it answers to a real tune.
Happiest boosted just enough — revvy and reliable, not a fragile dyno queen.
Old and new both live on K-series. Built to embarrass the badge.
The legend is real; the myth gets people hurt. Head studs and a proper tune before big boost.
World-class chassis, an engine that wants help. Built into the car it should have shipped as.
Huge power is easy. Keeping the trans and temps alive is the actual work.
The VQ loves boost or a blower once you fix its oiling and heat habits.
A blank canvas — SR, RB or LS. I build the swap that fits your goal and budget.
Rotaries reward respect and punish shortcuts. A proper rebuild is legend-vs-paperweight.
Best chassis-per-dollar there is. A modest turbo embarrasses cars worth four times as much.
EJ ringlands fail from lean tunes and heat — I tune Subarus to live, not to screenshot.
The Subaru twin — same world-class chassis, same honest engine that rewards a real tune.
A weapon that wants to be pushed — fueling and drivetrain that take the power instead of breaking.
Track weapons that overheat when you use them. Tune plus cooling unlocks them in SoCal.
Cheap, enormous power — right after the wastegates, walnut build-up and fueling, in that order.
Golf R and GTI — the EA888 answers to tuning like few engines do. Tune plus TCU plus the right mods.
Same EA888 magic in Audi trim — S3 and RS3 wake up with a tune, TCU and supporting mods.
Real power left on the table from the factory. A proper tune wakes them up without gambling the drivetrain.
Precision, not a parts cannon. Set up to feel factory-plus, never fragile.
Nobody says "I need suspension work" — they say "I'm building a canyon car." Each build page carries a three-tier ladder and the question no shop answers: can this still be your daily?
The best jack-of-all-trades there is — because it has to get you home.

If you paid for a tune and it made no power, something is wrong — and it's almost always one of five things: a canned flash that was never yours, a boost leak lying to the ECU, a fuel-system limit, heat soak, or a mechanical problem the last shop never logged. I find it in order.
You just bolted on your first upgrade and every set of taillights is a question. I'm not going to lecture you about the law — you know. I'm going to tell you where to actually go: the track nights, HPDE days and car clubs in LA that nobody marketed to you.
Every build follows the same disciplined arc: a baseline and a health check before I touch a map, incremental pulls with the logs open, revisions until the car is safe and repeatable across the rev range, and a delivery where I walk you through exactly what changed and why. No mystery, no black box.
That process is the same whether you're here for a stage-1 flash or a built-motor big-turbo project. See exactly how it runs on my build process page, or look through finished cars in the build gallery.
"Brought my WRX in after another shop's flash that made nothing. He found a boost leak in the first hour, retuned it on the dyno, and it finally makes the power the parts promised — on 91."
// Marcus R. · Rowland Heights · '22 WRX"Talked me out of a built motor I didn't need and set my S2000 up for canyon days instead. Most honest shop I've dealt with, and the car's never been better on GMR."
// Diana L. · Glendora · AP2 S2000"N54 finally runs right. Fixed the wastegate rattle, sorted the fueling, then tuned it. He does things in the boring order and it just works. Worth the drive from the South Bay."
// Kev T. · Torrance · 335iMy shop is in West Covina, in the San Gabriel Valley — one of the two great import corridors in Southern California. The near ring is minutes away; South Bay and canyon-country drivers make the drive because they want a shop that only touches imports.
