Franz shipped his M6 Purple Belt ATS-V to the Tapout Tuning shop so he could upgrade to the Mace Stage 1 cams, springs and retainers. After completing the dyno tuning, Franz’s car produced an incredible powerband making 608 whp! Even more impressive is how strong his powerband is past 7,000 rpm! This car is going to be an absolute riot to drive on the street and we know Franz is going to have a very fun ride home. #savethemanuals!
