When you talk about Powerstroke dominance and relentless innovation in the diesel world, one name stands out above the rest: Jesse Warren.
Founder of Warren Diesel Injection (WDI) and a longtime champion of Ford performance, Jesse Warren has spent more than 15 years pushing the boundaries of what a Powerstroke engine can do — and now, for UCC 2025, he’s back with a machine and a mission that could shake the diesel world to its core.
Jesse Warren is no stranger to the Ultimate Callout Challenge battlefield.
In the early years of UCC, he made his mark by bringing Ford power to a playing field dominated by Cummins and Duramax heavyweights. With smart tuning, incredible injector technology, and raw determination, Jesse consistently posted strong performances — showcasing that the Blue Oval deserved its seat at the diesel elite table.
Whether it was through high dyno numbers or pulling strength on Sunday, Jesse made one thing clear: Ford fans had a champion, and his name was Jesse Warren.
For UCC 2025, Jesse Warren is taking it to another level.
He’s rolling into battle with a purpose-built Pro Street Ford F250 4x4, featuring a full fiberglass tube frame chassis built for maximum speed, strength, and control.
Under the hood? A masterpiece of innovation — a 7.0L billet aluminum HEUI-powered engine based on the legendary 6.0L Powerstroke platform.
This isn't just another build. It's a declaration:
It’s the ultimate showcase of what 15 years of cutting-edge WDI experience can create — and it’s a direct challenge to every other platform at UCC.
Long before UCC, Jesse Warren was already redefining diesel competition with WDI injectors — known for producing some of the biggest and most reliable competition injectors available anywhere.
From daily drivers to record-setting race trucks, Jesse’s fingerprints are all over the diesel community.
His company didn’t just support the movement — it helped build it.
For Jesse Warren, UCC 2025 isn’t just another event. It’s a homecoming. It’s a battlefield where he can once again prove that Ford power, innovation, and heart still belong at the very top of diesel competition.
Armed with decades of experience, one of the most revolutionary Powerstroke builds ever assembled, and a team that shares his obsession with winning, Jesse Warren is coming back to make history.
Every diesel event, every innovation, every hard-fought battle in the shop and on the track — they’ve all led to this moment.
Jesse Warren: The Powerstroke Pioneer. The Innovator. The Relentless Competitor. The Legend Who's Just Getting Started.
