Paul from Pennsylvania stopped by for spark plugs and intercooler fill/bleed kit.  Once his car was running smoothly it made 428 whp and 436 wtq, which was on the high end of stock ATS-Vs.  Next we added our custom dyno tune, dialing in the WOT boost, fueling and ignition timing.  Peak power increased to 473 whp and 494 wtq, with gains of more than 50 whp in several parts of the powerband.  Pretty impressive for his 91-octane fuel!

Matias stopped by for our Blue Belt Performance Package, AWE Tuning cat-back exhaust system, GiroDisc brake rotors, Speed By Design ceramic brake pads and carbon fiber seatbacks.  He’ll be heading back to Georgia with another 100 horsepower, better stopping power and improved aesthetics too!

Chris came by with his 2024 CT4-V Blackwing in Cyber Yellow Metallic.  This is an M6 car that we upgraded with our Purple Belt performance package.  He ended up making 605 peak whp and 596 wtq, gaining 200 horsepower over the factory power level!

Seth from Michigan had us install colder spark plugs and EPA catted downpipes on his beautiful Velocity Red 2024 CT4-V Blackwing.  He left his intake and throttle body stock and we were still able to put down 506 whp. with our world class custom dyno tuning.

Sebastian from Michigan brought his beautiful 2026 CT5-V Blackwing with only 2,600 miles in for our very popular PD3 camshaft package, Kong Ported blower with a 2.3 pulley, NW 103 throttle body, K&N Cold Air Intake and Stainless Works Headers.  Final results were 746 whp on pump 93-octane with a conservative 13 PSI of boost.  This car sounds like a monster with the PD3 cam and Stainless Works Headers.
