Amazing experience with Kushan working his magic on my CTS-V Coupe. I was really impressed with his knowledge of the LSA platform, and his experience on various builds. His shop is immaculate and he really knows his stuff. I am very satisfied with the newfound power and will be using his services and expertise for all my future plans. I highly recommend Kushan and Excelsior Motorsports for anyone with an LS platform looking to take their build to the next level.

Kushan and his team did an excellent job tuning my 04 Silverado. Can’t recommend them enough, good tuning isn’t cheap but it’s a great value to know my GM truck runs better than it did 20 years ago!!

Complete waste of time dealing with this clown. For starters he rarely answers the phone, and when he does he tells you he will call you back and never does. Typical Socal trust funder attitude, setup by mommy and daddy and doesn’t need your business at the end of the day. Either that, or doesn’t care if you just want a small repair done and only wants the big jobs. Either way terribly run business.

I had Excelsior Motorsports recently diagnose a few issues related to my 2004 Corvette. The owner Kushan and his team did a great job diagnosing rather than just throwing parts at the problem (which many shops unfortunately do). Additionally, Kushan gave a honest, thorough assessment of their status which I appreciated. And all the work was done for a fair price, unlike other shops. Excelsior Motorsports is the real deal and up until now I had a hard time finding a good, honest Corvette or performance shop (btw, these guys work on most GM vehicles - doesn’t have to be a Corvette), but from now on this is the only place I will take my Corvette. This is also the only Corvette (and GM performance) shop I can recommend to others at this time.A warning though: since they are swamped with a lot of customer cars (either for tuning or making track worthy or just repairs and general maintenance) - a good shop is always busy - it could take some time before they will work on your car. So, if you need something done to your vehicle just plan in advance, especially if it’s a daily driver. Don’t procrastinate, just get a date on the calendar to drop off your car and be patient.

Had them tune an 09 G8 GT here a few years ago. Never had any problems with the tune they put in it. Was on the conservative side I was told by other tuners that worked on the car later. But fast service and very nice hub dyno.Service: Auto engine tuning

I highly recommend Excelsior Motorsports and Kushan for the work theyperformed on my supercharged corvette. Kushan, owner and expert engineer, trouble shot my corvette after it stopped every twenty minutes.It was diagnosed as a malfunctioning throttle body sensor. Kushan, on a mainline dyno run, found that the supercharged engine was detonating.He also installed a fuel pump that out performed a ZO6 pump. SeveralChevrolet dealers said they will only replace a stock pump at a higher man hour cost. Kushan, previously upon my request, installed a Ron Davis radiator that has a transmission and oil cooler. I also had Kushan do a chassis height adjustment and alignment, and a major tune, pulling additional horse power and setting fuel air ratios. This resulted in increased power, fuel mileage and no detonation, within California's C,A,R,B limits. Kushan, an engineer and avid race car driver knows corvettes! He drives one.John G.Services: Steering & suspension repair

Kushan and his team are the best at corvettes. I knew I was in good hands taking my C6 to get a list of things I wanted done to it. You get what you pay for and if you care about your corvette take it to Excelsior Motirsports

Excelsior is the best. Kushan and Zach have prepped two Vettes for me for track use and they know exactly what to do, because they do it themselves!Kushan is extremely knowledgable, patient and consultative about car setup and improvement. He also helps properly prioritize the stages of upgrades based on budget.I'm fortunate to be within 15 miles of Excelsior but if you're not, it's worth the trip to work with them!Services: Brakes

Excelsior Motosports was recommend to me on the C5 facebook group for tuning services. One of the best recommendations I ever received. I couldn't be happier with the results and the customer service I received. Truly a professional and extremely knowledgeable all around great guy. He tuned out low end hesitations and made it a fantastic street car with low end drive ability! Other tuners told me it couldn't be done. If you need anything done on your corvette stop shopping around and give them a call! I will definitely be back!Service: Auto engine tuning

I have a 2013 60th Anniversary C6 that was originally modified in Texas. I brought my car with me here when the military moved me from TX to CA and in the year I have been here I have been slowly upgrading and maintaining my car with Excelsior. I also daily drive this car and so far it has been bulletproof with Excelsior!First off, I am impressed that they have been willing to talk through and help me make long-term goals with my car. Equally impressive is they were willing and able to work on my car despite it having work from a prior shop. They originally did work to de-dyno my car from 93 octane to 91 (because it's at almost every pump in TX but not in CA).Secondly, I came back to add a big air box as well as some other upgrades to my car and he created a custom shroud around my intake just to go the extra mile! He didn't have to do this and that too impressed me. He finished with a couple other parts and fuel injector cleaning. Then he finished with another dyno and transmission tune. They have also done general maintenance on my car such as replacing the rotors and pads. And each and every time all I've had to do was call, set an appointment, and they get me an appointment no problems.Currently my car has an appointment to visit these guys again and after going here multiple times and loving it I decided to write this review to share my outlook on this place! Every time I drop my car off I get it back quickly. They always give me fair prices. And I have no issues making conversation with Kushan or any of his Techs while I'm dropping off or picking up my car. I don't go out of my way to write reviews often. But I wanted to give my full story and tell you that I like these guys!Services: Brakes

I emailed the owner 3 times in an attempt to get a ball park installation quote for services they claim they perform on their website. I don't have time to go in person and I wasn't price shopping as I was set on conducting business. However, the owner blew me off twice and never followed through. Having a fortune 50 business management background myself, I can understand picking the right business deals but if this is how he operates business I can see now that the negatives reviews about bad trade skills is true. I'd advise to be cautious when consulting with this guy and just make sure he follows through with what you want. I can't speak to his shop as he failed to negotiate business but I wouldn't trust him with my vehicle now.
