2007 Classic Chevy Silverado

Truck already has some "not saying name" plug in tune.

Comparing it to our 1999 corvette some things just don't look right. I've already done a lot of the transmission stuff that has worked for me in the past as well as knocked out what torque management I could remember that's there. The timing is all over the place. I do not have a wideband sadly..
