About Us
Welcome to DTP
At Diamond Tuning and Performance, it’s not about inflating numbers, it’s about doing things right.
I walk you through the entire tuning process, whether you’re chasing peak horsepower or perfecting a daily driver. Every tune is tailored to your build, with reliability and real-world performance at the core.
From HEMIs to LS swaps and everything in between, expect a personal touch backed by experience, data, and actual results.
No guesswork. No cookie-cutter maps. Just real tuning, done right.
We constantly train, test, and certify our skills to ensure you get the best results every time. See our certifications below.

What Our Customers Are Saying
Outstanding Dedication
“The owner Zy is a great guy. My truck has been trial and error and he keeps making sure it gets back running fantastic. No matter how many revisions, he will make sure the truck runs perfect. Thanks Zy for the fantastic experience and helping me out with everything!!!”
- Dakota Parks
Corvette Tuning Success
“Had him come tune my 2003 Corvette and he is really easy to work with and does an amazing job. Got the Corvette shifting smooth and running amazing. Not to mention faster 😅”
