Our friend Johnny drove in from Massachusetts to upgrade from Blue to Purple Belt. Even with catted downpipes, we were able to hit 602 whp and 632 wtq. Notice the big power dropoff above 6,000 rpm. This is a classic sign of weak valve springs on this 89,000 mile engine. We went ahead and reduced Johnny’s rev limiter and shift points for now to help keep things as safe as possible. At some point in the future, we will want to upgrade the valve springs on this car.

This customer was here just three months ago for a Purple Belt Package but just couldn’t wait any longer to upgrade to the Brown Belt Performance Package! After we installed Pure Stage 2 Plus turbos, ARP head studs, and few other supporting mods we strapped his car down to the dyno to really turn things up. His 2018 ATS-V left the Tapout Tuning Shop with 708 whp and 656 wtq! He plans to be back soon for methanol injection so we can push those turbos even further.

Zach from Texas worked with our partner Exodus Performance in Austin to upgrade his totally stock 2016 ATS-V to Purple Belt. Dyno results were 601 peak whp and 651 wtq on E51 fuel. This ATS-V is going to be a lot more fun to drive on the road now, and in the words of Men’s Warehouse, ‘we guarantee it!’.

Our friend Nick came here last spring for us to install our Blue Belt Performance Package on his clean M6 ATS-V. He loved the power gains but when spring came around this year he was hungry for more. Nick decided to step things up with our Purple Belt Performance Package and his car made 601 whp the go around! Needless to say, he was hyped about the power gains. But if we know Nick, we bet we will see him again next spring for our Brown Belt Package 😉

Brian brought his extremely rare Pedestal Edition ATS-V in for a Purple Belt Performance Package! 3,600 miles on the clock, a manual transmission, and the beautiful Bronze Sand Metallic paint make this ATS-V very special. Brian’s ATS-V made 621 peak whp and 615 wtq.
