Nacs Performance Diesel

Emil was amazing from start to finish. We took our truck in for a couple of issues it was having. NACS installed a new fuel sending unit, oil cooler, Sinister EGR delete, Sinister oil and coolant filtration system, injectors, and did a software tune. Truck already rides like a champ. It has amazing power and torque. These guys did an excellent job, and will be coming back to them as needed.

Hands down best diesel performance shop around emil the owner is the man bulletproofed my 6.0 an keeps it running like brand new always gets me in an out the door

Edit: it was a full 12 months ago that I had my truck delivered to Nac's on a flatbed. It still runs as strong and smoothly and RELIABLY as it did the day I got it back from them, and their customer service has been top notch to this day. I recommend anyone I talk to with a diesel to Nac's whether they need a mechanic at the time or not, and I keep their business card in my door pocket. I'm getting ready to move out of state, and my biggest concern is not being near Nac's anymore. Thanks guys for taking good care of me.

Nac's did a cab off job on my 6.0. They were faster, cheaper, and BETTER than any diesel shop around, and they had a lot full of 6.0's, in particular. The guys at Nac's got my truck done in less than a week by working weekends to get me in and out, and since then my truck runs like a scalded dog, reliably. I regularly pull my 15k 5th wheel confidently and with a truck that pulls it strongly. I've also had my dad's 6.0 in for diagnostics just so they could tell me what I needed to fix, and hit the nail on the head. The guys are good, fast, and extremely reasonable. They don't overcharge and they don't do things that don't need to be done. I just had my truck in the shop for something I thought would be entirely more complicated, but they charged me the minimum for a battery terminal, when I was expecting 3 zero's. They work is impressive, but they also exhibit incredible integrity, and I value that. After having just over a year's relationship with Nac's, I can't sing their praises widely enough.

The best diesel shop I've ever been involved with. A bulletproofed my motor no issues no problems great service always there for me when I need them hands down if you ain't using nacs you're missing out very dependable people very honest..

Great Ford diesel repair shop. Total bulletproof for $4500. They did good job. 2 year unlimited mile warranty. Repaired my 2007 F250 6.0. I pulled my truck from Tampa Greg Lane after his motor rebuild failed in 2018. Had to spend more hundreds. I am never going back to Greg Lane.

By far the best experience I've had at a diesel shop in Pinellas County. Emil's customer service was great. Called me within an hour of receiving my truck to go over the diagnostic report and get authorization to perform the repairs. Made reccomendations but wasn't pushy. Work was done quickly. Will definitely be returning in the future for more work/ upgrades.

Say what they do and do what they say. Bullet proofed the 6.0. Runs like a champ now.

These guys are the real deal. They are honestly the best and most reliable diesel mechanics I've been to. I have a recommended them numerous times and I wouldn't use anyone else.

Emil and his crew are true mechanics not parts replacer‘s I’m very picky about work done on my E350 6.0 They bulletproofed the motor and did a great job OMG what a difference.I would recommend them to all my friends and have.

Our number 1 diesel repair shop of choice. We send all of our Powerstrokes to them. 20 to 50 trucks a month. Always running perfect. Thanks Nacs Performance.

Emile and his guys are Great!! I called they pretty much diagnosed what was wrong over the phone with my truck after explaining to them the issues I was having. Dropped it off to them and was in and out in the same day thanks guys !!
