'13 Sierra Denali AWD 6.2L crew cab. BTR PDS Stage 1 torque cam, Magnuson TVS1900, ID1050x, 93 octane, SW full length headers, SW X pipe with converters, SW cat back. Hellcat TI Auto fuel pump. ZL1 converter (LSA)
Engine made 564/529 on an engine dyno N/A (were waiting on blower from Magnuson so just to break in/check leaks/etc it was ran with a LS3 intake/throttle body. Throw the TVS1900 on it with 9.5 psi boost I estimated 700hp in Summer and in Winter more like 750hp. Gets better than factory fuel economy. My only gripe is part throttle around 90kpa or so it will get into the 10.5-11 AFR sometimes. I feel like there is a balancing act with shift scheduling and part throttle high KPA are (but not quite in boost) Otherwise it runs excellent.
