Marty and Hms provide a great product and experience. Built a great drag car motor and his knowledge with his chassis dyno helped get the motor just right and maximize what we had in the car. Also went out of his way to check in on me as I was installing the engine and offer any help or advice I needed. Very pleasant experience and will be back for any other engine/tuning needs I haveRob

If you're looking for a real mechanic that knows what they are doing these are your guys. I pulled in with my race truck and just listening to it as I pulled on the dyno they already knew what it needed. They stopped everything got the parts I needed right then, installed them, then tuned it. We didn't finish until close to 11pm. They were there to do the job the right way and see it through to the end.Services: Auto engine tuning

Not very happy with the service I received. Had a 2003 Ford Mustang Mach 1 that needed a engine rebuild. The rebuild took over a year and ended up costing a lot more then what was said. Plus when I did get the car back, it drove fine for about 4-5 months then on my way to Tucson from New Mexico I was on I-10 going about 80mph and my transmission locked up. Had the car towed to AA All star and they found that the transmission was installed wrong. Marty said he would remove it and take it to AA All stars so they could fix it. A week later he told AA that he wouldn’t do it, it wasn’t his problem. I also found a drain tube going from the intake shaker to ground completely missing.I would not recommend HMS to anyone, save yourself the time, money and headache and go somewhere else.

First of all, Marty is a great guy! Pep Boys quoted me at $3500.00 and Marty took a look at what they diagnosed and he disagreed. He got the job done for $575.00 and even cleaned the car! Runs great..no leaks…no errors.Service: Engine repair

Marty did a tune on my 1955 Bel Air with a newly installed LS3 with a Holley terminator x-max system. I got the car running but I knew I needed someone smarter than me to finish the tune. Marty’s work tamed the beast and now she runs perfectly. I’m sure there are a lot of rear tires that will meet their demise as a result of his work. Thanks! DougService: Auto engine tuning

Marty is good people. And his guys are excellent mechanics. We have an older GMC 6.5 turbo diesel dually truck. Finding a good diesel mechanic can be pretty difficult. We were lucky to have a friend who referred us to this place. We appreciate you, Marty!

Great experience with this shop. Marty is a knowledgeable mechanic and was very fair with his pricing. When the electrical issue was solved and I came to pick up the bus, he walked around it with me and made sure everything else was working properly. He noticed the ac wasn’t blowing cold and quickly replaced a bad fuse on the spot. Went above and beyond to make sure everything was good to go for me. Would recommend this shop to anyone in the Tucson area needing reliable diesel service.
