Pat G Tuning

2012 CTS-V Coupe M6 makes 1192rwhp/1042rwtq at 20lbs boost running E85. It sports a Dart 427 block, FED M311 Boost Monster heads, 237/247 113LSA cam, ID 1700 injectors and a DMS 68/62 twin turbo kit.

1991 Camaro will surprise a lot of people making 802rwhp/632rwtq on 93 octane. The power comes from a forged LSX LS7 short block, PRC LS7 cylinder heads, 235/243 116LSA camshaft, ID1300 injectors and a D1X Procharger making 15lbs of boost. Tuned in speed density by Pat G and weighing only 3400 lbs, the 3rd gen Camaro is mighty quick.

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.

2001 Trans Am WS6 M6 makes 540rwhp/493rwtq on 93 octane. This stock bottom end LS1 runs a 226/232 114 cam, and is pressurized by a D1SC Procharger and fueled by 60lb injectors. Tuned in speed density by Pat G.
