I want to do the 411, but since I drive this every day, and I want to swap to a 4L80, gonna wait on the swap. It would make sense just to do it the 0411, but with the tune, there's nothing else to swap. Yeah I could tune the 0411 for the 4L60, but then would have to tune it again when swap to the 4L80.
Motor is all stock right now. Not sure what I'm gonna do to it. I was gonna do an LS 6.0, it's in the back of my truck, but that ain't happening any time soon. Right now it (will have headers soon), new intermediate pipes, no cats, 2 to 1 y-pipe going into a Borla XR-1 3" and 3" Dynomax tailpipe. Cold air kit too. Truck runs pretty good now. When I put the Borla on I lost some, think it flow too good lol, but gonna swap that out cause it drones in the cab something killer. Need some back pressure. I have 2 0411's, one is already set for a Vortec/4L80, would just need to swap the VIN. The other is for a 6.0 I think, not that it matters.
