After corvette servo install. 4l60e. 2006 gmc sierra with 35's.

Before you blab...speedometer is 10% slow and I know these arent "fast".... this is just to show its new acceleration under LIGHT throttle application with 35's. I'm reaching 50 mph that quick in a truck with 35's by giving it VERY little throttle...its impressive...versus it short shifting like crazy all the time and being a sluggish dog...definitely woke up the transsmission in this sleeping beast. I'd say it is a MUST with oversized tires.
