For the cars built to be driven harder than the dealer ever tested.
Mercedes-AMG biturbo. BMW M S58 and S63. Audi RS DAZA and EA825. Porsche GT3 / GT4 motorsport. Master-certified hands, AWD dyno on site, ECU and TCU calibration, big-brake builds, and track-day prep.
The factory builds the platform. We finish the conversation.
Every AMG, M, RS, and GT leaves Affalterbach, Munich, Neckarsulm, and Weissach with headroom on the table. Conservative ignition advance for global fuel quality. Soft TCU shifts to protect dealer-network warranty claims. Restrictor plates in the exhaust to meet European drive-by noise. Track suspension that ships set up to live with potholes. A platform built to handle far more than the spec sheet quotes.
Our job isn’t to make your AMG into something it’s not. It’s to remove the compromises the factory built in for somebody else’s problem — on 93 octane, with the right gearbox software, with the brakes and cooling sized for the new output, and with a stock file on disk so the car returns to OEM the day you sell it. Below: the marques we live in, the calibration stages, the track-prep checklist, and the dyno that keeps everyone honest.
The platforms we live in.
Every line below is something we have on lifts in any given month. The engine families, the gearboxes, the chronic faults, the upgrade paths — we can quote them from memory.

Three stages. Honest gains. Reversible to OEM.
Every stage starts with a baseline dyno pull, ends with verified before/after data, and ships with a stock file on disk. We do not deliver tunes by email and we do not flash anything we cannot back up.
Stage 1
ECU calibration only. Pulls the conservatism out of timing, boost, and throttle mapping. Optional TCU flash sharpens the gearbox without compromising longevity.
- ECU calibration to 93 octane map
- Optional TCU flash for shift feel
- Baseline + verification dyno pulls
- Datalog review across full RPM band
- Stock file archived to disk
Stage 2
Stage 1 calibration plus the supporting hardware the factory left out: high-flow downpipes or X-pipe, cooler intercoolers, larger intake, charge-pipe upgrade. Cooling and exhaust work that lets the engine breathe.
- Catless / high-flow downpipes
- Charge-air cooler upgrade
- Cold-air or carbon intake
- Re-calibration to new airflow
- Knock and AFR datalog verification
Stage 3+
Upgraded turbos or supercharger pulleys, port-injection or methanol, ARP fasteners, billet rods on the engines that need it. Built for clients chasing real numbers — not for daily commuters.
- Hybrid / upgraded turbo install
- Port injection or methanol kits
- Internal forging where required
- Clutch, axle, driveline upgrade as needed
- Full bespoke calibration on E85 / race fuel
Six pillars. One bench standard.
Performance is more than a horsepower number. The chassis, the brakes, the cooling, the rubber, and the driver all share the work. Six disciplines we hold to factory-or-better spec on every car that leaves the shop.
ECU / TCU Calibration
In-house tuning on the AWD dyno with knock, AFR, boost, and trans-temp datalog. Every flash backed up, every map reversible to OEM.
Forced Induction
Biturbo, single turbo, supercharger work on M177, M178, S58, S63, EA825. Hybrid turbo installs, charge-pipe upgrades, fueling.
Exhaust Systems
Akrapovič, Capristo, Brexhaust, ARH, IPE, Fi Exhaust. Catted, catless, valved. Sound clips and dyno data on file for most platforms.
Big Brakes & Pads
AP Racing, Brembo, Movit, Endless. Six- and eight-piston upgrades. Track-pad swaps coordinated to event calendars. Bedding documented.
Coilovers & Alignment
KW Clubsport, Öhlins TTX, Moton, Bilstein Damptronic. Corner-balance and four-wheel alignment on a Hunter Hawkeye to motorsport specs.
Cooling & Drivetrain
Oil coolers, transmission coolers, MQB / MLB axle work, clutch upgrades for the cars running real power. Built to live at sustained load.
AWD chassis dyno. On site. Honest numbers.
We don’t quote crank horsepower from a spreadsheet. Every calibration starts with a baseline pull and ends with verification — AFR, knock retard, boost pressure, transmission temp, oil temp, all in one log. You leave with a copy of every run.
Show up sorted. Get home sorted.
HPDE at Sebring, PCA at the Glen, NASA at Homestead, Gridlife wherever. We prep the car to series tech, swap pads and fluids on schedule, log tire pressures and brake temps, and have a debrief slot booked for the Monday after.
Pre-Event Inspection
Brakes, suspension, axles, fluids, belts, mounts. Photo file delivered.
Brake Service
Track pads, motorsport fluid (Castrol SRF / RBF600), rotor temp paint.
Corner-Balance & Alignment
Driver-weighted, full tank. Four-wheel alignment to motorsport spec.
Cooling Audit

Post-Event Debrief
Monday slot to review fluids, pad wear, datalog, and brake temp paint.
Four steps. Documented every time.
Consult
What the car is for. Daily, weekend, track. Power goal, fuel grade, supporting hardware budget.
Baseline
Stock dyno pull. Full diagnostic scan. Stock file archived. Health check on every supporting system.
Execute
Hardware install, calibration, verification dyno, datalog review. Texted progress with photos.
Deliver
Final road test, before/after dyno graphs, stock file on USB, written summary of every change.
The ones every performance owner asks.
If yours isn’t here, the phone is the fastest way. Lester or one of the tuners picks up most weekdays.
Call (305) 740-3440 →Tune-specific powertrain claims can be denied if the OEM detects a tune. The factory warranty on unrelated systems remains intact under the Magnuson-Moss Warranty Act. We always discuss the trade-off honestly before any flash — and we keep a stock file so the car can be returned to OEM mapping at any time, with no fingerprint.
Yes. AWD load-bearing chassis dyno on site, rated to over 2,000 WHP. Every performance flash is verified with before/after pulls, AFR, knock retard, boost pressure, and full datalog review. You receive a copy of every run on file.
Yes. Fluid swaps, brake pad and rotor service, suspension corner-balance and alignment, transmission and PDK service, tire pressure logging, and a full pre-track inspection. We work to Porsche Motorsport intervals on dedicated track cars and stage parts in advance for back-to-back weekends.
Yes. We build cars for clients running NASA, SCCA, Gridlife, and PCA. Bolt-on packages, KW / Öhlins / Moton coilover installs, big-brake kits (AP, Brembo, Movit), cooling upgrades, half-cages, seat and harness integration. All work documented to series tech requirements.
Highly platform-dependent. A Stage 1 ECU calibration on a C63S M177 typically gains 60–120 crank horsepower and 80–140 lb-ft of wheel torque. Add Stage 2 hardware and you’re at 200+ crank. Stage 3 with hybrid turbos and fueling is a different conversation entirely — we’ll quote real numbers from real cars in your platform, not from a spreadsheet.
Yes. Every car we flash has its stock file archived to disk. We can return your car to OEM mapping the day you list it for sale, with no flash counter, no fingerprint, no calibration ID change. Many clients tune to drive and flash back to stock before service visits to the dealer.
Yes, on a labour-only basis once we confirm fitment and quality. We’ll let you know honestly if a part isn’t up to the job. Most clients prefer we source through our channels — Akrapovič, KW, AP Racing, Capristo, and the OEM-equivalent suppliers we already deal with directly.
Bring the car. We’ll finish the conversation.
Calibration consult, baseline dyno, full build, or simply a fluid swap between track weekends. The bench is open.
