I finally had a truck come in for a dyno tune it was actually hassle-free, so I knocked it out real quick. This 2007 classic Silverado is sporting a Truck Norris camshaft from Brian Tooley Racing along with a FTI torque converter, long tube headers, TBSS intake manifold with a LS3 throttle body and some flex fuel injectors to handle the extra airflow. This video is to demonstrate the importance of keeping your commanded AFR safe during the tuning process in the event that the actual AFR ends up being much leaner than what you are commanding. A wideband O2 sensor is a necessity for this process in most vehicles, but especially GM vehicles that only have narrowbands from the factory. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #4pointgreat #lsx #btr #BrianTooleyRacing #diy #howto #hopethishelps #mechanic #mechanicsoftiktok #racetruck #trucknorris #cam #camshaft #LFG
