Another ATS-V with Caddy Issues turbochargers, another 700 whp powerband! We did a Purple Belt Performance Package with Mace Stage 1 camshafts last spring. Kurt enjoyed that for the last year, then shipped his car in from Tennessee for some more upgrades. We installed ARP head studs and Caddy Issues turbochargers, and strapped it back to the dyno. Kurt’s incredible powerband tells the story.
