No baseline, no proof. Every car gets a stock pull before the work starts and the same run again when it is finished, which turns “it feels quicker” into two curves you can lay over each other. Baselines catch other things too. A boost leak, a lazy wastegate, a filter nobody changed since 2019, a coil pack going down — all of it shows up as a soft spot in the curve. Cheaper to find it now.

A calibration is only valid for the fuel it was written on. We develop maps for 93 octane pump gas, 100 and 110 octane, race gas and E85, and each gets its own dyno session, because ethanol content, knock resistance and the fuel volume the injectors must deliver all shift together. E85 is the underrated option. It cools the charge and resists knock hard, and on a turbocharged car with the injector headroom to feed it, that is frequently the cheapest real power on the menu. Nitrous and water/methanol systems get calibrated here too, the sane answer to a Georgia August when heat is stealing your timing.

We reprogram the factory computer rather than lie to it. A piggyback intercepts existing network data and hands the ECU altered signals, which holds up until the car’s own protection strategies notice the mismatch and start pulling timing or cutting torque at exactly the wrong moment. A flash changes fueling, ignition timing, boost targets and torque limits in the tables themselves, so the computer makes correct decisions with correct information. Off-the-shelf files fail differently. They were written on somebody else’s car, in somebody else’s climate, on fuel from somebody else’s pump. Pass-thru devices stay on the bench for the platforms that need them, and remote tuning is available through our online store for owners too far out to bring the car in.

One example, with a date attached. A B5 Audi S4 2.7 twin-turbo built in this shop made 780 AWHP, and on 13 September 2013 it ran ten half-mile passes at WannaGoFast at Heaven’s Landing in Clayton, Georgia, averaging 149.83 mph. That took Fastest Four Door out of 157 entrants, on a private 5,069-foot mountain runway. A shop-modified 996 Turbo has also won at WannaGoFast in Ocala, Florida. Results carry venues. Brochure numbers carry logos, and only one of the two survives a timing beam.

Yes. The Mustang unit is 4WD and load-bearing, so quattro, 4Matic, xDrive and ALL4 cars run with every wheel driving. Two-wheel-drive cars use the same rollers in the appropriate configuration.

Tune for the pump you will actually use, which is 93 octane for most street cars here. E85 is worth a serious look on a turbocharged car with enough injector capacity. Race gas and 100 or 110 octane maps make sense for track weekends, and a car can hold more than one map on the same ECU.

Yes, with hardware and files handled through our online store, for owners outside the metro. A car we can get on the rollers always ends up with a better map. Remote is second best.

That is precisely what it is for, provided there is a baseline to compare against. We record horsepower and torque before the work, run it again after, and hand you both curves. Without the first run, the second one is just a number.
