Diesel Repair & Performance

Diesel trucks work for a living around Seminole. The shop handles both diesel repair and diesel performance — what's wrong, and what you want next.

Tell the shop what the truck is doing, or what you want it to do, and Jorge will tell you whether it's a fit and what makes sense from there.

Mon–Fri, 8:00 AM – 6:00 PM · Appointments Mon–Fri

Common reasons customers contact us

  • The truck runs, but not like it used to
  • A warning light, a code, or a noise you can't place
  • Hard starts, rough running, or smoke you didn't have before
  • It struggles with loads it used to pull without thinking
  • You want more out of it — towing, response, or all-around performance
  • You're planning performance work and want it thought through before parts get bought

These are examples of what customers bring in — not a list of everything the shop does, and not a promise about your truck. Every job starts with the shop confirming fit.

Who this is for

For anyone running a diesel pickup around Seminole and the surrounding area — work trucks that earn their keep, daily drivers, and trucks their owners want built into something more. Repair and performance are both welcome conversations here.

What to send

  • Year, make, and model
  • What it's doing — or what you want it to do
  • Any codes, sounds, or recent history worth knowing
  • How the truck gets used: towing, work, daily driving
  • Your name and phone number

What we can discuss

  • Diesel repair — figuring out what's wrong and fixing it
  • Diesel performance work, planned around how you use the truck
  • Custom tuning for diesel work
  • Repair and performance modifications on trucks

If what you need isn't listed, ask anyway — Jorge will tell you straight whether the shop can take it on.

How it works

  1. 01

    Send the details

    Use the request form or call the shop with the vehicle, the symptoms or the goal, and how to reach you.

  2. 02

    The shop reviews fit

    Jorge looks at what you sent and tells you whether the shop can take it on.

  3. 03

    Diagnose or talk it through

    Repairs usually start with getting eyes on the vehicle. Performance plans start with a conversation about the goal.

  4. 04

    You approve before work happens

    You get the shop's recommendation first. Nothing moves forward without your say-so.
