Dale from Tennessee shipped his car to us for Blue Belt mods.  Even with catted downpipes, he’ll be driving home with a BIG powerband!

Exodus Performance in Texas did a very nice job upgrading Sean’s 2016 ATS-V to Brown Belt status.  Peak power is now above 700 whp starting at 5,600 rpm!

Bryan shipped his beautiful blaze orange metallic 2023 CT4-V Blackwing to us to install Purple Belt upgrades.  He ended up making 593 peak whp through EPA catted downpipes on a 98 degree summer day.

Matt came in from Indiana with his 2023 CT4-V Blackwing to have our wildly popular Purple Belt Performance Package installed.  He ended up making 591 peak whp with E53 fuel in the tank, and should be well into the 600 whp range when he increases his alcohol content to somewhere in the E60 to E70 range.  That’s the sweet spot for these cars.  Below E60 we need to pull back boost and/or ignition timing.  And above E70 we can run into fuel system capacity issues.

Danny from Virginia brought his 2022 CT5-V Blackwing in for the PD3 camshaft package with fully automatic flex fuel.  Final results were 769 whp on pump gas and 818 whp on E60 fuel.  This car sounds like a monster with the Corsa exhaust system!
