Rated R Performance LLC 7350 Eckhert Road, San Antonio, TX 78238

"Great customer service . Nathan took time out of his busy day to fix a few things on my truck and got me taken care of. My truck runs great with the tune he did . I’ve also taken few vehicles for a dyno tune and the driveability is always on point. Would gladly take my cars back to Nate for a tune."

"Awsome experience every time I take my car in. Rated R truly go above and beyond with there work and customer service. I consider my car as a fun showcar and their eye for detail is excellent with clean installs. Rated R took my mostly stock WS6 Trans Am that made 320whp and heavily modified it up to OVER 500whp. No worries if you get TUNED BY RATED R!"

"Awesome customer service and prices. I Took my 08 Silverado in for a cam swap and loved how honest and helpful they were with all my questions. They took the time to help me find what I was looking for while keeping my budget in mind.Not to mention how smooth the truck runs now with the tune. Never felt better. I WILL BE BACK."

"brought a camaro in for cam and tune. Was done within a few days and car drives like stock. The crew at rated R is fantastic and very helpful. Will continue to bring any other cars here"

"Met with Nate about bringing my stock C5 corvette to life. We came up with a good list of modifications for a good price. Work was done fast and neat. Nate is very knowledgeable at what he does and I would recommend Rated R Performance for any performance upgrades."
