A flash on a 4.7-liter V8 Vantage or a 6.0-liter V12 buys you single-digit horsepower, and anyone promising more is selling a graph rather than a result. Airflow is the lever on those engines. Higher-flow exhaust, sports cats, intake work, and on the V12 a header change are what move the needle, with the calibration written afterward to match what the engine can now breathe.

That order matters. Parts first, then the map, then the verification pull. Doing it backward means paying to tune the same car twice, and we would rather tell you that on the phone than after the invoice.

Every Aston booked for performance work gets measured before anyone touches it. That is not ceremony. The baseline pull catches what owners do not know about their own car — a lazy pre-cat oxygen sensor, a soft coil, a boost leak on a DBX that spent the winter parked, an exhaust valve stuck shut. Fixing those alone sometimes returns more than the tune would have.

Our Mustang dyno is load-bearing and 4WD, which matters for a DBX. V8 and V12 cars run in 2WD mode on the same rollers, boost and air-fuel ratio plotted against rpm, so the graph shows where power arrives rather than where a brochure claims.

A DBS Superleggera with 715 horsepower is limited by its rear tires long before it is limited by its engine. Start with the rubber. So the useful upgrades on a fast Aston are frequently not engine upgrades at all: a proper alignment, the right pad compound for how you actually use the car, fresh brake fluid, and tires that suit the season.

Carbon ceramic rotors need matched pads and a bedding procedure, not whatever fits. Fuel economy will still be poor, and that is not the map’s fault — aggressive driving alone costs roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic.

No. Our factory certifications cover BMW, Audi, Volkswagen, Porsche, MINI and Mercedes-Benz, and our techs are ASE certified. For Aston Martin we work as an independent specialist with dealer-level scan equipment, an in-house dyno, a fabrication bay and race-prep experience.

It can. Manufacturers can read flash counters, and a modified powertrain gives them room to decline a claim. If the car is still covered, we would rather walk you through that risk before the ECU is written to than have you discover it at a service desk.

93, from a station with high turnover. The maps we write for street use assume 93 pump gas, because that is the best fuel reliably available here. Race gas and E85 maps exist for track cars with the fuel system to support them.

Yes. Both use the twin-turbo V8, and the DBX707 already runs elevated boost from the factory, so the gains come from calibration refinement, exhaust flow and cooling rather than simply asking for more pressure.
