Had my car retuned here because P&L motorsports doesn’t know what they are doing. Harold fixed P&Ls mistake and my car is running beautifully. Harold is very knowledgeable and knows what he’s doing and doesn’t beat around the bush. Definitely recommend dynosource performance for all your tuning needs!

Put headers on my wife's trail blazer SS and Harold was able to add about 40 horse (350 wheels) plus way better drivability compared to stock. Hope to be back after more upgrades.

I have worked with Harlod for over 20 years with all of my performance needs. Everything from 4 cylinder to big block applications. He is my go to for anything performance related. I have always and will continue to consult him and use his services. Top notch and very knowledgeable.
