Performance Specialists
Brandon was able to take my stock 2006 LS2 C6 with 7,000 miles from 330whp to 471whp by working with me and recommending high quality performance parts. He took the time to get the shift points down and dyno this car so it drives like it should. The added power and sound is amazing. Brandon and his crew are very experienced. They packed up my take off parts and helped me load them up. Brandon and his wife Jordan were both quick to respond to questions during this build. I would recommend Lethal Performance & Dyno for your performance needs. I will continue to go here for service as well as future upgrades.

06 C6 LS2 performance
Brandon took my 100% stock (even the tires) 2006 LS2 Corvette from 330 whp to 471whp by installing only quality parts in a professional manner. This shop is the place to go for all your performance needs. His employees organized and assisted with loading the take off parts and were always professional. His wife was very helpful with the billing and reassuring of my decisions. I would not trust my car to just any shop and spent considerable time researching prior to the build. I will only trust them to the ongoing service needs. Brandon worked hard to get the shift points just right for me. He was open to my concerns and addressed any items that I was unsure of. He is very busy but it is worth the wait.

Carol said she went to get the turn signal on her vehicle repaired. She said she sat for 1 hour, not knowing what they had done to her vehicle, and the cost was $66 for the repair, and that was a high price. She said she was not pleased with their explanation on the cost and the time she spent there. She said she did not have a good feeling after she left, and another business did her differential, and it cost much less. She said the bottom line was she got better service at another business along with a free rental on a vehicle.
