Meet Steve Dinan

Steve Dinan, a pioneer in improving, tuning, and enhancing performance, possesses a relentless curiosity that drives him to question the status quo. Throughout his career, he has consistently asked, "Why is it made this way? What happens if this is changed? Can it be improved and why?" For Steve, driving is not just a mere act but an ongoing classroom, where every maneuver and modification becomes part of an ever-evolving if-then statement. Each change made to a vehicle serves as a learning opportunity, and through careful observation and analysis, Steve's confidence in his craft continues to grow. He understands that the cars themselves possess a language, and by developing an empathetic connection, he can discern whether they appreciate or reject the modifications.

Performance Software

CarBahn’s performance software is designed to deliver reliable “Smooth Power” meaning the software is calibrated correctly by using a safe approach to power adjustment. Excessive torque will break the tires loose, overload the engine and ruin the drivetrain. To reach optimum power, the software is easily combined with our high-performance intercoolers/heat exchangers and turbos.
