Heard great things about this place and got recommended by a friend but sadly they did not seem very interested in Fixing my car or even provide the services there known for i went in 2 times, called about 4 times and even spoke to Shane simply said they would get back to me and never did. Wish their costumer service was better or even bother to call back and say they cant work on my carService: General repairs & maintenance

These guys know what they are doing and it shows. JR and Shane are both extremely knowledgeable and their pricing is on par with the quality work they do. I’ve had my truck tuned by them twice in lieu of numerous modifications and a built transmission installed along with some other new drivetrain components. Transmission had issues from the manufacturer and JR helped me deal with the manufacturer and the issues with the trans all while installing it in a timely manner. Truck runs great several months later and I have peace of mind that my money was well spent. They have gained a long term customer with what I have seen from them.

I have an LS swapped car. When it came time for the tuning J&S was amazing. They were able to give me a base tune with just the ECM out of the car. Doing this allowed me to iron out any leaks or problems with the build. After the build was complete I took it to them to finish the tune. While the car was there they even repaired one of the pins on the OBD2 port that was giving them a little bit of a fit. JR and Shane are extremely knowledgeable. I highly recommend using them!

Have gone to these guys a few times now, they have dyno tuned my car, fixed some stuff me and my buddies installed, and are ALWAYS super up front and professional. They don’t hide things, they don’t bait and switch like most shops, they actually care about your car and in my opinion are the EXPERTS on LS engines in Colorado. From what I’ve seen they do dodge, chevys, and most any of your boosted/muscle cars. These guys are no joke. They really have experience and know what they are doing and will help you reach any goal. (As long as you have the budget of course.) you certainly are paying a premium but in my opinion it is worth every cent and then some because you are getting BEYOND premium service. Can’t wait til I can pay these guys to procharge my Camaro SS. Stop debating, go to this shop for your car. Period.

These guys are the BEST!! I asked on a Facebook group who they would recommend, and J&S was the most suggested. I am so extremely happy I took my Procharged Corvette to them to have the differential swapped out. While doing the programming they found issues with the tune and with the Procharger installation. They corrected all these issues and now my car runs better than it ever has. My Corvette is a Show car and they treated it as such as they promised they would, and they called me after I drove the car to insure I was happy with the tune and the job in whole. Their pricing was very reasonable, in the future this will be the only place I take my Vette and my other vehicles for any needed work I cannot perform.Services: General repairs & maintenance

Amazing shop! I brought my Cadillac Cts-V to this shop to get some oil leakage fixtures and a tune. When i took it up the first time for the oil leaks they were letting me know everything was going well and if they found other small problem that i did not know about in the car they would let me know right away. JR and Shane are both great people and very knowledgeable. Would 100% recommend this shop to anyone!Services: General repairs & maintenance

These guys are awesome! Talk about performance automotive knowledge. Not only that but they are honest! They hooked me up with the necessary components to make the pro charger kit I put on my Silverado actually perform properly. I always had problems after putting the kit and the guys at J&S were the only shop that knew what needed to be done. I’m really enjoying the truck now! Thanks a ton guys! See you when I’m ready for the next upgrade!

Took my C7 Z06 in for a tune, pulley, and shocks, but brought it in butchered with additional problems from another horrible shop. For J&S this was no problem and they did an absolutely astounding job. They not only installed every part I had asked for perfectly, they took their time with a tedious problem, assessed it, and then provided me with the quickest solution. The car has ran great, at its fastest since leaving the shop with no additional issues. JR also guided me towards better steps to take in the future with the vehicle as well as calling me a month later to make sure everything was still 100%. I will be coming back to J&S for all my corvette needs; They are, speaking from personal experience with tons of other shops, the best automotive shop I have worked with in all of Colorado.Services: Auto engine tuning

Recently took my c5 z06 corvette to J&S after having misfires and other issues that I just could not find the cause for. These guys did an amazing job finding and solving my issues. Finished the job a few hours ahead of scheduled time and the car runs AMAZING! super happy with their service and would recommend to anyone with an LS/LT. Not to mention their prices are fairly reasonable
