2009 CTS-V A6 arrived with terrible street manners mostly due to the 5” cold air intake getting hit with turbulent air in the brake duct. The mass airflow sensor would get freaked out at highway speeds and wreck the fueling making the car buck and surge. The solution was to tune it in speed density. The result was 690rwhp/696rwtq on 93 octane. Mods include a BTR stage 3 cam, 2.38 upper pulley, 8.66 lower pulley, RPM 5” CAI, ported blower, and long tube headers. Boost was 14lbs. Street manners are now superb.
