This customer is used to ultra powerful cars.  So she dropped her new CT4-V Blackwing off for Brown Belt upgrades  We left her with three separate tunes – one for 93-octane pump gas.  Another for pump gas with methanol injection.  And a third for ethanol fuel with methanol on top.  Good luck keeping up with her 736 whp powerband!

Matt was lucky enough to score a 2022 CT4-V Blackwing with less than 2,000 miles on the odometer.  We worked with HP Tuners to unlock his ECM, then we installed our wildly popular Blue Belt Performance Package treatment.  Another Blue Belt car, another 100 whp gained.  It’s also worth noting that the Blackwing Burble effect sounds even sweeter in M6 cars with our resonated downpipes!

Rob drove his 2016 ATS-V A8 in from Tennessee to get the Blue Belt treatment with catted downpipes.  Now his car drives as nicely as OEM, and makes an additional 100 whp!

Casey from Louisiana worked with our recommended shop Exodus Performance to install and remote dyno tune the Purple Belt Performance Package.  Net results for this M6 car were 613 peak whp and 619 wtq.

Brian just picked up a 2023 CT4-V Blackwing with in the new Midnight Steel Metallic color.  We worked with HP Tuners to unlock his ECM, then he came back for the full Blue Belt Performance Package treatment.  30 hours later his car had picked up well over 100 whp and was a completely different animal.  Now Brian is ready to maximize his smiles per gallon rowing through the gears.
