My 1983 BJ46 Land-Cruiser had recently undergone a restoration essentially sitting undriven for a year. My objective was to pick up my vehicle from Kansas (restoration location) and return home to Alaska. The initial stretch of the trip was uneventful until I arrived at Limon, CO.Embarking on the 2nd days travels I filled up with diesel and added a diesel additive to clean the fuel system…immediately after my BJ46 felt over fueled and underpowered; maintaining 45 mph was difficult. I replaced the fuel filter in Cheyenne, WY with no change in performance.Very fortunate my travels brought me through Casper, WY to Second Wind Performance. Steve and Raleigh examined my BJ46 and diagnosed the issues as gumming fuel. I purchased their recommended fuel additive and based on their usage guidance the vehicle was fully performing after 3 tanks.Steve and Raleigh went above and beyond on this chance encounter and I am grateful our paths crossed. I would highly recommend anyone seeking knowledgable, genuine, and passionate expertise to contact Second Winds Performance.

Was passing through town and wanted some work done that I couldnt get done in my home town. They were able to accomplish the desired work and some additional fun work. They were very respectful of my time needs and helping me identify the correct solutions while being price competitive. Couldnt recommend more!

Niles was amazing!! Great customer service and knowledge of what was happening with my car, speedy service done right, and an affordable price.

Great service. This shop got me a price that beat the internet on a set of Fuel rims. The few people I worked with, both on the phone and in person, were all personable. The work done was satisfactory and the employee I worked with was enthusiastic. Id likely go back for other work.

If you have the unfortunate to have to break down in any state and youre in a diesel fingers crossed youre close to second wind performance. I was on the road for almost 7 days before I found them. They treated me with the utmost respect!! (And I was on the road for 7 days Plus 😮) they got my truck in same day and got it fixed. Then a straggler part came in the next morning. Im just going to put this out there if you have to drive two or three states away and you need work done on your diesel it is worth the drive to come to the shop!!! All their technicians are extremely cool and very knowledgeable professional!!! And they do extremely well work!! I would highly recommend them for any diesel work that you need!

Excellent help very noledgeable with lift kits very concerned about the safety of your vehicle hard to beat service like that

It is exceptional the only place Ill take my truck

Excellent work!! Had motor replaced on my Ram 2500, Jade did an excellent job!! Steve was great to work with as well!! Highly recommended!!

My wifes truck had emissions issues 3 days before needing to travel over 1000 miles for a funeral. Called and found out they were booked up but after talking with Steve he got the truck in first thing the next day and got it all fixed up properly. Everything that was installed was very clean and looks great. The truck runs flawlessly now. The customer service I experienced was over the top and ill definitely be doing more business here in the future.

I called left my number they never returned my call. And its for a big job.

I barely made it into Casper Wyoming when I blew up my turbo charger on my 2001 f250 7.3 diesel. It was Sunday so after doing a little research I found second wind performance in Casper and I called him first thing Monday morning they had to turbo on the shelf and after a little mishap with ordering the pedestal the guys did an excellent job, very professional, Scott the mechanic was exceptional. I recommend these guys highly and I would use them again!

My experience wasnt really the best to start off. I even left a bad review on here but now updating it. Honestly it was probably me more then these guys. I would highly recommend these guys to anyone even though I thought they was a little too expensive and spilled gas in the back bed of my truck. We are all human and make mistakes. Im sure they think Im one bipolar mood swinging dude. Im really not guys. Just a lot of money we were dealing with. They do know what they are doing and I should had listened to them instead of arguing. Sorry guys.

We were traveling when our transfer tank developed a leak. They worked us in and fixed our problem. Would recommend their service.

Steve opened the shop on a Saturday to work on my 2018 Ram. I was impressed with the knowledge and attention to detail. Also, his daughter detailed the inside of my pickup and washed my windows. Bless her heart, it was DIRTY!!!

Been a diesel mech for many years spoke to several guys at the shop jokingly about a red head gear box they knew exactly what i was speaking of. Very knowledgable staff, good experience, truck still needs the darn ball joints replaced after platinum garage fried my diff lack of oil, but it handles better will be going back .

They have me and my ‘12 Cummins a completely new lease on life last year. I have moved away but have made 3-4 trips back (1000 miles one way) just to bring my truck to them for upgrades and regular maintenance. Trustworthy and reliable, have got advice and help when I’ve ran into trouble 1000’s of miles away and had to have repairs done someplace else. They are Rockstars and I’m very grateful to Steve, John, and everyone else there for the service!!! Won’t go anywhere else for work on this continent!

Very knowledgeable and fast professional service.

I have been going to second wind over 10 years and just recently decided I won’t be going back. After 2 weeks for a front cover and oil cooler I got it back after paying a bill that was $1000 over quote, then had to take it back because there was no glow plug in cylinder 2. Parking brake wasn’t hooked up. And now I’m currently limping it to a different shop because my turbo is losing pressure. This is all within a week and half of getting it back.

Very honest and knowledgeable staff. I had many questions and they were all addressed until I was happy with the answer. I never felt rushed or upsold. I even inquired as to a few upgrades and to whether or not they would be worthwhile for my setup and they gave me honest answers and even talked me out of doing some of them because there would be no benefit. I was blown away by the service and quality of the work performed. They caught several small maintenance issues proving they were very thorough. Best experience I have had with a shop. I will be back for any repair or service I need.

Great place

Very helpful and nice people

Im so late with this review, I feel embarrassed. Earlier this summer came off the freeway in Casper and my Dodge 3500 was smoking and banging like a blacksmiths hammer! Crawled to our RV site. The next morning started calling around. Friends referred me to Second Wind. Talked to Louie and he diagnosed it right off the bat. Had it towed to their shop. Within 6 hours I had new injectors and was back on the road. The truck runs great! Thank you to the Second Wind crew!

Great to work with, excellent work, and professional. I had several upgrades done to my truck and it turned out great. I will keep going back.

Great diesel service!!

Went in to order an edge eas egt probe. Turns out had them in stock. Made my day!Friendly service and knowledgeable.

Hands down the best diesel shop in town.

Went here for years but wont be going back. Place has become frustratingly incompetent and the management dismissive and arrogant. I wouldnt let them work on a Tonka truck.

Great place Great folks

Excellent shop, I have been taking my truck there for years. Every time I get it back the job is well done.

(UPDATE) Bolt on my turbo pedestal cross threaded and burned in.(UPDATE).If i could change this to zero stars i would.. keep finding so many things wrong. Wiring harness ran wrong, coolant lines ran wrong, disgusted.Vacuum lines left unglued, nuts and bolts left on my whiper cowl, the rubber boot on my turbo to charge pipe wasn’t tight (blew off on the way home). Broken plug left unplugged with exposed wires. Cold side charge pipe put in poorly and was crimping my coolant line. Will never take another vehicle there.

Well if you have any truck needs such as exhaust or lift kits take your truck to 2nd performance these guys well get it done right the first time thanks again john Penrod Im a satisfied customer

Would not recommend this place

The guys are great, smart and do an awesome job!

They do great work and professional!

Steve and the crew are freaking awesome !!!!!

Not only did these guys fix my Duramax but they explain to me in layman terms what was wrong with it I will never go anywhere else but here

Really expensive with poor attitude to boot

Very responsive and professional had my truck in and out in the time frame they gave me Kudos
