Superior Automotive is located in Southern California having relocated in the 1990's from New York where Joe Jill had established Speedwin Engineering in 1960. Superior Automotive quickly gained a well deserved reputation as one of the finest state-of-the-art high performance automotive services, diagnostic and repair facilities in the U.S., just as Speedwin had from the 1960s through the 1990s.
Carburetion and fuel injection systems are tested under actual running conditions using the chassis dynamometer. Under load, the fuel system and fuel curve are analyzed; fuel pressure and volume are checked for each application. Our Fuel Injection service cleans, matches and calibrates injectors. We can maximize performance and mileage by achieving balanced fuel flow.

Bad experience, bad outcome, bad business, going out of business. Ruined my engine by negligent management. Failed to provide an estimate for cost of dyno services, failed to get authorization for reported repairs that were not done to spec nor completed, and overcharged for services not rendered. I felt defrauded.

Joe, Dan, Tad, Arlene and the whole crew at Superior Automotive did an excellent job on my old 1966 Mercury Station Wagon. They took my old motor and breathed a whole new life into it with high performance parts and tuning. Now my old 66 runs INSANE. I had one VERY minor issue, but they stand behind their work and fixed it immediately. I HIGHLY recommend Superior Automotive! Thank you again to the whole crew! - Frank Red Hot aka The Donut Man;

They did machining on many many blocks and heads for me over there. I wouldn't go anywhere else. No BS, the proper equipment, the proper people with the right knowledge. Never had a delay, always on time. As a matter of fact I just shipped a head over there from the midwest, rather than dealing with "shops" here (yes. shops in quotes lol).

Great job on identifying problem with my car. Fixed MAS and after tuning it ran great. Idle was not so good. They stood behind it and told me to bring it back, and let sit overnight so they could redo idle tune. As they leaned it out quite a bit with replacement of MAS. Have that planned this week. Stay tuned. Tad knows his stuff. I Felt real comfortable. Of course to get the best you must pay accordingly, so don't look for cheap here. Arlene in office is my kinda person, no bs. just the facts. good sense of humor also.

Hi, I went to this place to get done the recalibration of gear ratio in my 2014 Mustang. The guy named Tad, worked on my car (for about 35 mins) and ended up damaging the Computer of my car. First he came to me and said he couldn't recalibrate the gear ratio and stated that his programmer is not compatible with my computer. Right when I left the shop, my engine light came on so I came right back to ask him what he did. (i waited for him to come back from lunch).
Then he acted like he did not even worked on my car when I ask to get the receipt of what he did and the results. He refused to give me the copy of the papers (that I signed) and also refused to give any receipt of what happen or what test he performed. So, I had to call the police on him. When deputy came, then Tad give me the copy of the papers that I signed only, He refuse to give me any receipt and stated that no work was performed.
Please do not trust these people, they are big liars. Specially that Old lady that sits in front, she is the biggest liar out of all there. Please get all copies of EVERY Paper they ask you to sign before they start work on your car and CAREFULLY read everything they ask you to sign. They are big fraud and liars. I don't want anyone else to go through all that I had to go through with them. My car is in another shop now since Tad damaged it, so I will be sending them the bills of all the repairs. Good luck.

There are very few shops I trust with my car. Recently, my car, 2009 Pontiac G8 GT, needed some TLC and I had some upgrade parts I wanted installed. -Fuel pump -Headers -Full 3 exhaust -Injectors -Plugs & Wires -Suspension bushings & Sway Bar -S/C Pulley -Dyno Tune Having known Tad (their tuner) for a number of years, I knew Superior Automotive was where I was going to take my car.
All the parts I brought them were installed in a timely manner and it was all done right, no issues. The car drives like a different car now. as well it should. 2 thumbs wayyy up for the team at Superior!

I had experiences with this place like 2 years ago and nothing, but problems. Tad (the tuner) had an attitude, and I had to keep coming back because my car kept getting CEL's. bad tuner. Then he silenced my exhaust without asking me and said that he didn't want me to get pulled over. Bs then when I go back for him to put the old tune back in he's like "this isn't something we normally do.
I only did it for you" something like that and that pissed me off. But I stayed cool and that was the last time I ever went to that place. Went to Cunningham Motorsports a few months later to get retuned and Flex fuel installed and amazing! Car has no issues, great service, and I go there for all my modding needs. Do not recommend superior automotive.
Don't get me started about how they messed up putting my 1" lowering springs on and I had to get them fixed at project import which is another shop that I have work done to my car. I recommend them and Cunningham Motorsports highly!
