Straight answers about how our diagnostic and calibration work is structured, what you need to bring in, and what happens after the first pass on the dyno.
Both. For stock ECUs we use bench flashing and OBD port access depending on the platform. Standalone installs are handled separately with a full wiring review before we start mapping. If you are unsure which route fits your build, send us the ECU part number and we will confirm the options before booking.
We pressurize the intake system to the boost level your setup runs, then check every coupling, weld, gasket, and the intercooler core itself. We use a regulated air source and soapy water to find even small leaks. You get a written report with photos of any problem areas and a recommendation on whether a repair or replacement is needed.
Yes. Factory turbos respond well to calibration changes, especially when the wastegate duty cycle and fuel tables are adjusted within safe limits. We will not push a stock unit past its efficiency range just to chase a number. The goal is a reliable curve that holds up in real driving conditions.
A typical session runs four to six hours on the dyno, depending on the platform and how many maps we need to build. That includes baseline pulls, fuel and ignition adjustments, boost control setup, and a final street verification if the car is road legal. We do not rush the process, so bring a full tank of fuel and plan for the day.
Bring a list of all modifications, especially the turbo size, injector flow rate, fuel pump capacity, and any boost controller settings. If the car has a log from a previous tune, include that too. The more detail we have about the hardware, the fewer surprises we run into during the first pulls.
Yes, for a limited period after the session we answer questions about cold start behavior, part throttle response, and any adjustments you want to try. If a hardware change happens later, we can discuss a re-tune session. For urgent issues, use the contact page and mention your vehicle registration number so we can pull up the file quickly.
Workshop services and technical formats
Every service below is built around a specific failure mode or tuning goal. You bring the car, we bring the pressure gauges, smoke testers, and a clear sequence of checks that ends with a number you can trust.
We pressurize the entire intake path from turbo outlet to throttle body and listen for the leaks that kill response. Using a regulated air source and a custom test cap set, we find split couplers, cracked intercooler end tanks, and worn throttle shaft seals that a visual inspection would miss. You get a leak report with exact locations and a priority list for replacement parts.
We measure actuator crack pressure with a hand pump, compare it against the spring rating, and set preload so boost comes in early without spiking. For external wastegate setups, we check diaphragm condition and adjust the boost controller gain to eliminate oscillation. The result is a stable boost curve logged across third and fourth gear pulls.
Using dual pressure sensors before and after the intercooler core, we measure pressure drop at sustained load and compare it against intake air temperature rise. This tells us whether the core is flowing well or becoming a restriction. We also inspect fin condition, internal oil contamination, and charge pipe routing for unnecessary bends.
We pull live fuel trims on a warm engine, look for vacuum leaks, failing MAF sensors, or clogged injectors that push long-term trims out of range. When needed, we bench-flow injectors to confirm delivery rate and spray pattern. This service is a prerequisite for any safe tuning session, because a lean condition under boost destroys pistons fast.
We work with stock ECUs and common standalone systems to adjust fuel and ignition tables within safe limits. Before touching the map, we verify fuel pressure, compression, and base timing. Then we log knock counts, exhaust gas temperature, and wideband AFR during controlled pulls. The goal is a calibration that holds up on the street, not just on the dyno.
After any mechanical or calibration change, we put the car on the dyno to measure actual wheel horsepower and torque. We run three consistent pulls, correct for ambient conditions, and hand you a printed graph with the before and after curves. This is how you know whether the new intercooler or wastegate setting actually did something.
Workshop feedback
"Used the boost leak testing procedure on a customer's 2.0T. Found a cracked intercooler coupling that two other shops missed. The soapy water method from the article saved us a full afternoon of guessing."
"The wastegate preload guide got my own track car running consistent boost for the first time. No more spiking at high RPM. I now set actuator pressure with a hand pump before every tune session."
"Intercooler pressure drop measurements from the site helped me talk a client out of an oversized core that would have hurt response. We logged intake temps before and after and the numbers spoke for themselves."
"ECU mapping fundamentals section cleared up fuel trim corrections for me. Applied the steps to a stock turbo Subaru and the idle smoothed out within two drive cycles. Straightforward and practical."
"The dyno test analysis breakdown is the reason I finally understood how to read a torque curve. Used it to explain a mid-range dip to a customer instead of just saying it needs a tune."
