Mark and his crew did an outstanding job installing my Procharger on my C7 Grand Sport Corvette. They back up their work and the product they sell. Over the top experience! Highly recommend Speed Sports for any task!

Not very happy had one of my ecm's tuned once before. This time I took in my ecm for another vehicle. One tech was helpful the other was super stand offish. They took it in got it done in a fast manner. I took in a simple fan enable tune paid 350 bucks. Took it home plug and play fans don't come on. Troubleshot it found the ecm has no ground output for either of the fans. Im a mechanic myself for empire know what I'm doing. Deal with ecms all the time. Tried to call all day no call return. Would like to just get my money back. Sent in the ecm ups I hope it gets figured out. I'm not a person to complain at all but I paid top dollar for the service live hours away.

Mark was amazing, had a situation with my tune on my LS3. Mark was able to get it tuned and back on the street. Thanks again for caring about your customers and doing an amazing job.

Been to Speed Sports to set up an appointment for the past 3 months Talked to the owner both times. Put me on the list both times for an appointment. First time he lost my number.The second time he said he was going on vacation an when he got back he would get me taken care of. Said he would be gone a week ...... that was 3 weeks ago. Still waiting.Terrible Customer service

In August I had brought my 2012 Silverado that I built with my father to Mark. Because this was my father’s first and last engine build (so I’ve been told) I was very particular with who I trusted with it. Mark and his team were recommended by a friend that has had great experiences with them; now I can certainly say I’ve also had a great experience with this team. Mark took the time to ensure the 6l80 transmission shift points were exactly how I wanted and did a great job with the engines tune profile. My 5.3 went from completely stock to supercharged, a cam, long tube headers and a triple disc lockup converter. It runs flawlessly and the idle is perfect. I am very pleased with Speed Sports, Mark and his team. I would trust them with any future builds. Thank you.

Mike is a great guy that owns it. If you need to restore an old car this is the place to go

Brought another 360 sprint car engine to Mark for dyno and tune. Engine needed a lot of love but as usual Mark took the time to make sure everything was just perfect. Thank you Mark and team for the great service. I would give 10 stars if possible!Service: Auto engine diagnostic

I took my engine in for dyno tuning. was told 1-2 weeks, on week 2 sorry it wont be done I'm goin to the races. I would avoid this place is word is worth nothing. He didn't even reassemble my engine. He doesn't even answer his phone.
