I have a Magnuson super charger on my 2014 Yukon Denali, 6.2 liter engine. It has been professionally tuned on a dyno. We added bigger injectors and did a separate tune for E85 fuel mix. The dyno has the engine at ~650 HP and 680 ft-lbs of torque. It drives great. This has the six speed transmission and all I have read is this transmission is good to the 700 ft-lbs of torque at the flywheel. I have been driving the vehicle for 4 years now, just doing regular maintenance on the Severe Duty schedule to be careful. So far all is still doing great. The vehicle has headers,catback exhaust system and has been lowered 2”/4”. The supercharger really wakes up the performance of an already great vehicle.
