Meet the Tuner: Bobby Ervin
Long before he was behind a laptop dialling in a MoTeC map, Bobby Ervin was behind the handlebars.
He started racing skis back in the early 2000s, cutting his teeth in 750 Super Limited on Super Jets before moving through the Light Ski class on SXR800s, and later running limited classes on the Hydraspace S4 — "a great little ski," as he puts it. That stretch of racing is where the passion for performance really took hold. Bobby raced at Lake Havasu from 2008 through 2010, capping it off with a 2nd place finish in Pro-N Limited at his final Havasu event — a result he still counts as one of the highlights of his racing career.
That podium was also a turning point. Bobby stepped back from racing to go all in on the engineering side of the sport: engine building and tuning. He spent years behind a dyno cell, learning how mechanical changes and tuning work together to get the most out of an engine — knowledge that would take him well beyond jet skis.
From there, Bobby moved into motorsport at a much bigger scale, tuning MoTeC-based systems for V8 Supercars — primarily with Dick Johnson Racing, working through the Gen2 and Gen3 era. That meant race weekends all over the country, pulling and analysing data, and building tune files that had to hit tight targets for both fuel efficiency and outright performance. His motorsport career also took him overseas, tuning for Porsche motorsport teams at two of endurance racing's toughest tests: the Nürburgring 24 Hour and the Dubai 24 Hour, working on the RSR platform.
That combination — years of dyno time, and years reading data at the top level of Supercar and endurance racing — is exactly what Bobby brought with him when he joined the WORX team in 2023. MoTeC is still one of the core tools WORX uses in R&D today, well before a tune ever reaches your ski's OEM ECU. It's the reason WORX tunes aren't just about outright power — they're built to be reliable first, and quick second.
These days, Bobby's focus is on getting the most out of WORX's newest platforms, including the GP1800 and C2325. He's also at the centre of one of WORX's most exciting projects: WORX Racing RTD, developed in partnership with HP Tuners — and what it opens up for OEM ECU tuning going forward.
