Deke’s ATS-V

This ATS-V ONLY has a Gigs ported throttle body, colder spark plugs and our Tapout EPA catted downpipes and made 502 peak WHP. Not to mention, our dyno room was at 96 degrees during tuning!

 

It also has a CTS-V cluster swap. We don’t carry these, but we think it’s cool. Would you do it?

Meet the Team: Jorge

Meet Jorge, our Master Technician! He owns a 2016 ATS-V that puts down 738 WHP and 724 WTQ. Jorge was one of Scott’s very first ATS-V tuning customers and has been working here at our shop since the beginning! He initially came for a few weeks at a time from Florida, and as the business grew, he and his family moved here to Columbus, Ohio! This guy knows the LF4 like the back of his hand. If you’ve ever had parts installed at our shop, it was done by Jorge!

Tuned Escalade V Pulls

What car do you think has the best sound? We think this LT4 V8 exhaust noise combined with its supercharger whine is hard to beat. Custom headers don’t hurt either 😉
