Real 5-star reviews from our customers on Google.
“Stef is an absolute professional at his work. No doubt about that. I came in for a delete and tune, 5 inch straight pipe and got my truck back quickly. Not only did he just do the work, he explained the process, and soon to be fixes, and went beyond just any regular mechanic. I'm extremely happy with the outcome and look forward to continuing truck maintenance with Stef.”
“Full delete on my F350, great price, great service, went above and beyond to make it easy for me, 100% would recommend.”
“We brought our 5500 to Stef at superior for a delete. Did an awesome job. Didn't have to swap the ecu and truck runs great no lights on the dash or anything. I would highly recommend.”
“Had my truck at The Stance Shop and they recommended Stef with Superior Performance and I ended up doing a full delete with him. No issues, great communication and pricing. Will definitely be back and will send my buddies his way.”
“Brought my vehicle in to see Stef and he took care of everything for me in as little time as possible. Great service and response time, I would highly recommend coming here!”
“Stef has gone out of his way to get me what I needed for parts and went over and above to help the people install the parts. Only regret I have is not bringing my truck directly to him. Don't make the same mistake I did and get him involved from the start. Save yourself time, money and frustrations by dealing with Stef.”
“Great at what they do & at a affordable price.”
