Straight answers to the questions that come up most often in the workshop, from boost leak testing to ECU mapping. If you don't find what you need here, the contact page is the quickest way to reach the team.
Start with a visual inspection of all charge pipes, couplers, and clamps. Then build or buy a boost leak tester that fits your turbo inlet, pressurize the system to about 10-15 psi, and listen for hissing. Use a soapy water spray on suspect joints to confirm the leak. Common spots are intercooler end tanks, throttle body gaskets, and worn silicone couplers.
Wastegate preload sets how much boost pressure is needed to start opening the wastegate. More preload means the gate opens later, which raises boost. Less preload lowers boost and can cause boost creep. Use a hand pump with a pressure gauge to measure actuator opening pressure, then adjust the rod length to hit your target.
Measure intake air temperature before and after the intercooler with a pair of thermocouples, and log pressure drop across the core at the same time. A good street intercooler should keep pressure drop under 1.5 psi at your power level. If you see more than that, the core is too restrictive for your setup.
Start with a datalog of boost, fuel trims, and ignition timing at part throttle and full load. Look for fuel trims that are consistently positive or negative by more than 10 percent, which points to a vacuum leak or a failing fuel pump. Then check fuel pressure under load with a gauge before touching the tune.
For a stock turbo, oil and filter changes every 5,000 miles are the baseline. The turbocharger itself should be inspected for shaft play and oil leaks at every service. If you track the car or run higher boost, shorten that interval and check the compressor wheel for debris damage more often.
Log boost pressure, intake air temperature, and exhaust gas temperature during a third-gear pull from 2,000 rpm to redline. Compare your boost curve to the wastegate actuator rating. If boost rises slowly or spikes at the top end, the wastegate may be undersized or the boost controller settings need adjustment.
Whether you are chasing a boost leak, dialing in wastegate preload, or trying to make sense of a fuel trim log, the Injecturbo team can point you in the right direction. Reach out with your engine code, current setup, and what you have already tested. We answer workshop questions directly and keep the advice practical.
Reach the Injecturbo team for diagnostic help, tuning questions, or article corrections. We answer technical queries within one business day, usually faster during weekdays.
Email us at info@injecturbo.com with your engine platform, current setup, and the specific fault code or symptom you are chasing. For urgent workshop issues, call 028 043 1592 between 08:00 and 17:00. We reply to written queries within one business day and phone calls are returned the same day when possible.
Include the vehicle model and year, turbocharger type, boost pressure readings, any fault codes, and what you have already checked. Photos of the intake piping and wastegate setup help us give a more precise answer. The more context you provide, the faster we can point you to the right test or adjustment.
We can review datalogs and map files sent by email, and we will walk you through the relevant corrections over the phone. We do not provide remote flashing services, but we will help you understand the tables and parameters you need to adjust in your own software.
Yes. Send us the component or platform you want covered, and we will add it to our editorial queue. Popular requests such as wastegate rebuilds, intercooler pressure drop tests, and fuel injector cleaning guides are usually published within a few weeks.
If you spot an error in a guide or have newer data from a dyno session, email the details and we will review the article. Corrections are logged and published with a revision note so readers know the content has been updated.
