Commercial Truck Repair in Lakeland

“If you have a Duramax, this is the only shop you should be taking it to. I took my 2003 LB7 in for a full set of injectors, and the team at Twin Diesel Performance went absolutely above and beyond. Not only did they install the S&S SAC00 injectors perfectly, but they were incredibly thorough—replacing all the soft fuel lines and heater core fittings, and resealing the injector cups to make sure the job was done right the first time.
​What really impressed me was their attention to detail and quality control. They didn't just throw parts at it and hand me the keys; the tech took the truck on a thorough test drive to make sure everything was completely heat-soaked, holding pressure, and running flawlessly before sending the final invoice. They even left detailed notes on the condition of my factory hardware (like the injector return banjo bolts).
​The truck runs like a completely new animal—no more haze, incredibly crisp throttle response, perfect balance rates, and a rock-solid idle. On top of the stellar mechanical work, they worked with my hectic work schedule to make sure I could pick the truck up hassle-free. Honest, professional, and true diesel specialists. I can't recommend them enough!“

“Took my 2000 gmc 1500 5.3l to johnny for idle issues and uncalibrated sensors. Went to several other local shops and they all gave me the run around and kept charging me without fixing the problem. Johnny took my truck and figured it out within minutes. He explained to me the entire process. He took out that junk IAC valve and replaced it with an oem ac delco one he had at the shop. He then recalibrated my sensors so everything was working in sync with one another. My truck idles and runs better than it ever has! Back story: Johnny and Miss Ashley took me in over 7 years ago when I was practically homeless. They gave me a job and fed me and my 4 year old son at the time everyday! They took us in and treated us like family! Miss Ashley would take time out of her busy day and watch little Charlie so I could work with Johnny. After about 6 months, I got the call that I got the job at Lakeland Electric. Johnny told me that he hated to see me go but loved to see me win. I stuck with Lakeland Electric and now I'm a Lineman serving my community! When I say they are great and honest people, I really mean it with all my heart! Absolutely best mechanic around!!!
