Nathan was one of the very first CT4-V Blackwing owners to have our Tapout Tuning Downpipes installed on his car last year. Not long after that, he upgraded to our Tapout Tuning Module (TTM) so he could start to get a better feel for what this car’s potential was.
Of course, you know how the story goes…. Newfound power is always great until before long, you’re left wanting more. When duty calls, we’re there to answer, so Nathan brought his CT4-V Blackwing back to us for the Purple Belt Performance Package!
We installed the AutoTech HPFP internals, Tapout Fuel Cam, and Global B Flex Fuel Kit. This gives us the ability to create a tune that will automatically adjust anywhere from E0 all the way to straight E85! Nathan’s Blackwing left making 579 whp on 93-octane fuel and 651 whp on E60! This is our most powerful Purple Belt car ever; so, what’s the secret sauce you ask? We upgraded the stock turbos to the Pure Stage 2 Plus set, so he’s making more power with less boost! In order to keep things safe and reliable, we left the boost turned down. Nathan’s planning to upgrade further down the road, so he’s already one step ahead!
