Sin City Performance 520 West Sunset Road, Henderson, NV 89011

"These fine folks took in my Nissan GTR to fix a broken transmission pressure seal. They had the transmission out, shipped to be fixed, and back in within a week. They diagnosed the fueling issue, the tune, brakes, and it was ready to go back on the road, and for a price that was more than fair. Thank you, Sin City Performance."

"I took my 2015 gmc sierra for a custom tune and these guys could not get it down. I spend $3,981 with these guys and had took it back multiple times to get the tunning right. Last time I took it the truck ended up worse than the first visit. I finally found a man named Garth at leading edge performance and made things right. Garth ( leading edge performance) simply erased sin city’s tune off my truck and installed his; the truck is now running amazing. Came to find out that the Tunner at sin city did not know what he was doing and they made me believe that my fuel injectors, spark plugs, etc where the problem, and of course me believing to make my truck run again I payed these guys. I wouldn’t recommend sin city; at least not your newer vehicles! Keep in mind that I gave this over 2 weeks of driving my truck all over the city with Garth’s ( leading edge performance ) tune in my truck to prove that my truck is now running perfect with a simple tune that these guys at sin city just could not do."

"I purchased a 2020 modified Challenger Hellcat out of state. When i turned the car on when it came off the transport, the check engine light came on (it had not been on when i drove the car out of state). I received a suggestion to take the car to Sin City Performance since the Dodge dealership would not work on such a modified car. Sin City advised me that the car would require significant work including the fuel pump and fuel rails and possibly the engine itself. The out of state dealership where I purchased the car was going to cover these expenses but wanted another opinion given the cost. The car was towed to Leading Edge Performance (they were recommended on the Hellcat Facebook page). Leading Edge determined that none of the work that Sin City wanted to do was needed - it was simply a matter of updating the tune software file to match the modifications made to the car. Bringing it to Leading Edge enabled me (and the out of state dealership) to avoid significant unnecessary costs."

"I gave them not once, but two different opportunities to build by engine correctly since the first build my LQ9408 stroker it gave me nothing but problems last time I dropped it off. It Was more bad shape than when I dropped it up. I took it to leading edge performance they verified that it was not honed right and it was just put together very sloppy so it would’ve never ran right they do not want to take responsibility or pay me Any money back some more than likely I’m going to have to take them to court I have numerous of pictures to prove That they did not build it correctly and I’m not the one to take people to court. I would be happy if they were just to pay the shop what I spent to fix correctly. I also purchased a high-pressure oil pump And it was never used on my bill. I don’t know what happened to it come to find out. Doc also works there. He sold me some AFR heads said they were from a build from a guy. They just never finished the build, so he sold them to me, believing that they were in good shape turns out They were really used in bad condition so be careful with these guys, especially Doc. He’s really shady I would go to a different shop. You say that you tried, you didn’t try all you did was take my money and rip me off And I will be taking you to court everything you wrote on there was a lie Instead of taking my engine block like you said to a shop, you decided to board it out And you overboard two of the Pistons and I have a video of it When they went to take it off, it just literally flopped out. That’s why the engine was burning so much oil because you overboard it like I had You just don’t want to admit that you messed up then I asked you to shoot me just a few hundred dollars back so I can get it done right but you denied The offer still on the table you either shoot me 4grand or I’m gonna sue you in court for the full amount. I don’t care how much it cost me in lawyer fees, but we will be And I will post every process of the way even if I lose on this And I will be attending LSF and I will also let people know how shady your shop is I’m a man of my word I thought you were too, but instead all you did was take advantage of me and steal thousands of dollars and waste my"
